The Elks get a second offensive lineman on this list in Mansfield. The junior comes off the line of scrimmage with a low pad level. His pad level allows him to be under defensive linemen’s pads, and when he does that, he finishes his blocks multiple yards from the line of scrimmage. When a defensive lineman does not cover him, Mansfield’s long strides eat up a lot of ground and quickly get him to the second level. The Elk River junior can keep defenders’ hands off him with great push and arm extension.

I’ve been saving the adjective “mammoth” for the likes of only a couple of these Midwest Tall Boys, the first of which being Elk River, Minnesota’s 6’10, 300 lb. mammoth OT Cooper Mansfield. I just saw this dude live and in person during December’s PrepRedzoneMN Showcase, and I can verify his size from our measurements and scales. Mansfield is so tall that you can’t help but stare at his sheer size, and seeing how he’s coming out of the 2022 5A state champion Elk River Elks, it’s fair to say a lot is going for him on the gridiron. We’re not the only ones to think so either, as MAC competitor Ohio became Mansfield’s first offer a week ago in exciting fashion. He also visited Northern Illinois and St. Thomas in what was a busy January for the junior.

Playing in a run-heavy Power-T offensive attack that the state of Minnesota does very well, Mansfield isn’t well-versed in pass pro, but he makes up for it by having to play very low and with a ton of necessary bend, otherwise, you won’t see the field. Pad level is a must for the Elks offense, and Mansfield won the low-man battle a ton in his junior film from 2023. He can play on either side of the LOS and looks skinny on tape, plus was lean in person as well. The frame is a massive ball of clay for a D1 nutrition program and S&C coach, and to top it off he displays good balance, solid strength, and the effective ability to shoot his hips into contact. Mansfield has a great get-off and runs his feet once he gets engaged and comes out of his stance with enough power to run DL backward and sometimes spin them around in confusion like a dreidel. Good overall body control on a top 1% OT height/frame-wise. The words “big ball of clay” once again come to mind as I leave you on this evaluation.

One of the most impressive athletes on the hoof was Elk River’s Cooper Mansfield Cooper Mansfield 6'10" | 300 lbs | OL Elk River | 2025 State MN . The junior checked in at 6’10” and a very clean 275 lbs. Despite the 275 lbs, it is clear there is plenty of room for the junior to continue to add size. I was impressed by how well Cooper moved at that size. He was able to get good depth on his pass set vs speed. The junior used his length to his advantage, making first contact and controlling defenders throughout his reps. Cooper has traits you can’t coach, and a solid athletic profile to go along with it. He is a high ceiling prospect to know in the Class of 2025.
