Position projections and the discussions surrounding them are often fluid. That is certainly the case with several of the top prospects in Wednesday’s updated Top247 rankings for the 2021 recruiting class. Here 247Sports provides a quick rundown of the most noteworthy players who generated position debate during the most recent of rankings calls and discussions.

DONOVAN JACKSON, OFFENSIVE GUARD — COMMITTED TO OHIO STATE

The 6-foot-4, 308-pound five-star played left tackle for Bellaire (Texas) Episcopal, wrapping up his senior season earlier this month. Jackson has been projected since last summer to offensive guard following his outstanding performance at The Opening Finals as one of the few underclassmen competitors. At that event, he recorded a strong shuttle time for a player of his size with a 4.63-second run. That particular combine event often proves predictive of success for interior offensive linemen.

However, while Jackson is not the tallest offensive lineman, he is tall enough, especially when considering his verified wingspan in the 6-foot-11 range. That length, combined with his foot quickness and lateral mobility, could easily keep him at offensive tackle in college and beyond. In Jackson’s case, the position discussion is splitting hairs. He is likely an elite prospect at tackle or guard. Another thing to consider is how common the roster and positional needs dictate long-term positional home for offensive linemen coming out of high school. A player of Jackson’s caliber could play just about anywhere on the offensive line and it won’t surprise us where he winds up in the long term. Jackson is ranked No. 6 overall in the updated Top247.

JAMES WILLIAMS, SAFETY — COMMITTED TO MIAMI

Williams is one of the most unique prospects in this class. The Plantation (Fla.) American Heritage five-star moved from an athlete designation to a safety projection as part of this week’s update. At 6-foot-5, 218 pounds, Williams obviously does not fit the typical physical profile of a safety. But his play says differently. He is a smooth, easy athlete with a natural feel for playing in the secondary, especially in situations that allow him to play center field and patrol large pieces of territory.

At the same time, there’s obviously the real chance that Williams adds some mass to his enormous frame, and that could dictate a move to linebacker. Williams owns the frame of an edge rusher with the game of a defensive back. What makes him so unique as a prospect also makes him so hard to pin down from a specific position projection. From a comparison standpoint, the obvious name who comes to mind is Isaiah Simmons, Arizona Cardinals rookie and former Clemson star. The bottom line is the Hurricanes have a real gem in Williams, who should become an impact player regardless of his long-term positional home. Williams sits at No. 12 overall in the new Top247 rankings.

DALLAS TURNER, WEAK-SIDE DEFENSIVE END — COMMITTED TO ALABAMA

Listed at 6-foot-4, 235 pounds, Turner certainly owns the on-paper physical profile of the weak-side defensive end designation labeling him. He plays like it, too, with pass-rush production from hand-in-the-dirt and standing edge alignments. But the high four-star’s pursuit ability and relative fluidity for a player of his size and role would allow him to play some off-ball linebacker snaps if needed. He could realistically own the outside linebacker projection, and within that, could fit a 3-4 hybrid OLB or the traditional off-ball linebacker role.

Given Turner’s build, it’s likely he adds some more mass and indeed plays on the line of scrimmage in college, whether outside with a hand on the ground or as a standing edge. But we also acknowledge Turner’s stout build through the core and his closing speed in pursuit are intriguing in the context of a run-and-hit linebacker. We expect Turner to become a pass-rushing terror in college, but his potential versatility could also provide personnel flexibility. Turner comes in at 14th overall in the updated Top247.

JA’TAVION SANDERS, ATHLETE — COMMITTED TO TEXAS

Sanders is another unique prospect with the potential to become an impact player at multiple positions. In the high four-star prospect’s case, those positions include both sides of the ball. Sanders remains in his athlete designation, as that most accurately represents where we view him. He’s a true two-way athlete, and while the belief is that he will play the defensive edge at Texas, Sanders could easily stick on offense as a flex tight end or even a big outside receiver.

The 6-foot-3 1/2, 220-pound Denton (Texas) Ryan playmaker has produced impressive numbers as a pass-catcher and a pass-rusher, though he does not play full-time snaps on defense because of his offensive workload. It’s true that the belief for a long time has been that Sanders’ ceiling is higher on defense, but the more context we get, the clearer Sanders’ potential on offense becomes. Sanders’ ball skills and athleticism shine on offense, and he brings a lot to the table in the sense of a matchup problem. Sanders is ranked No. 26 overall in the new Top247.

SHEMAR TURNER, DEFENSIVE TACKLE

The DeSoto (Texas) defensive lineman has gradually gotten bigger during the course of his high school career. He has remained the quick, athletic defensive playmaker we have come to expect. Now in the 6-foot-4, 280-pound neighborhood, Turner moved from strong-side defensive end to defensive tackle in this week’s rankings update.

The reality is that Turner, a strong four-star, could play a number of positions depending on scheme and personnel. He’s big enough and strong enough to fit inside, but also shows the functional athleticism of a player who can live on the outside in a traditional four-man front if needed. Turner’s college destination will obviously play a major role in his long-term positional home. The Dallas-Fort Worth Metroplex prospect has a top five of Alabama, Georgia, LSU, Texas, and Texas A&M, in alphabetical order. Regardless of where he winds up, expect a front-line stalwart. Turner sits at No. 56 overall in the update Top247.

RAHEIM SANDERS, ATHLETE — COMMITTED TO ARKANSAS

The Rockledge (Fla.) four-star standout is an offensive playmaker expected to play receiver once he’s suiting up for the Razorbacks. However, in the 6-foot-2, 210-pound neighborhood, he has the look of a big back or even a linebacker. There is definitely reason to believe he could excel on the defensive side of the ball given his combination of athleticism and size. Sanders’ overall athletic profile, which includes basketball and track, also contributes to his potential as a playmaker at the next level, regardless of position.

We are high on Sanders’ potential as a big-play wideout in college. Having said that, we admittedly are quite intrigued by the idea of playing him on defense. All of this is reminiscent of another big-bodied athlete who already plays for Arkansas: Treylon Burks. Even larger as a high school prospect at 6-foot-3, 220-plus pounds, Burks has proven that playing wideout in the long term was the right move for him, so perhaps the template has been set for Sanders’ future. The update Top247 finds Sanders at No. 160 overall.
