Breaking down the tiers of offensive guard prospects…
ICONGlenn looks more like a guard than tackle to me.
David DeCastro: Stanford (6-5, 310)
The best offensive line prospect I've evaluated since Maurkice Pouncey in 2010. He showcases the ability to get a push in-line and is a dominant move player as well. He's fluid/natural in pass protection and with a little more power in his base he's got the skill set to become on of the leagues best guards early in his NFL career.
Cordy Glenn: Georgia (6-5, 348)
Has had some struggles in space as a tackle prospect, but in tighter areas where he can get his hands on linemen quickly as a guard he showcases the ability to dominate. Looks like a starting caliber OG early in his NFL career.
Amini Silatolu: Midwestern State (6-3, 324)
He has some technique flaws that needs to be fixed and will need to kick inside at the next level. However, he's a wide-bodied athlete with a powerful/explosive frame, good foot quickness and can really pull from the backside. Might need some time, but is one of the top guards in the class with as much upside as any.
Brandon Brooks: Miami (Ohio) (6-5, 343)
Is a big, strong kid who has some lateral quickness for his size but needs some technique work. Nevertheless, has some upside and can win consistently in the run game and pass game and looks like an NFL starter in an angle scheme to me.
Kevin Zeitler: Wisconsin (6-4, 315)
A tough, strong in-line guy who you can run behind and also has some coordination on the move. Not as effective in the pass game, but can mature into an average NFL pass blocker if he learns to get off the ball more consistently. Looks like a gritty type starter early on in his NFL career to me.
