Not a lot of info on the Colorado OT. The always-excellent Dane Bugler from The Athletic had this to say:
We know NE has done a great job coaching up corners and OL. Sherman looks like another late-round project for the staff.Sherman is an active player with trained eyes and movements, but his footwork and balance after contact need continued work,” Brugler wrote. “His lack of core strength and control at the point of attack will be tougher to mask at the NFL level. Overall, Sherman has workable traits with his lower-body flexibility and awareness, but his balance issues and wandering hands must improve for him to earn steady work in the NFL. He is a tackle-to-guard projection with some upside at center.
His eyes stay vigilant and his veteran experience is easy to spot... Pairs his wide base with solid thickness in his rear and legs…physical run blocker and flashes drive power…played in every game the last three seasons.
