Blaze and Estes can play. Blaze will be a good fit on the strong side in the 4-3, but I don't know if he can play in space. The guy hits like truck and seems to have the quicks. Avoided injuty this year which is huge. Estes, not the power center, but could fit in with a team that operates a lot in the shotgun like the Patriots. I think he is a pure center, not bulky enough for a guard. Good technique and if you watch him he has great balance, is rarely knocked off his feet, and uses his hands well. Kia - free agent tryout, but will get a shot. Tough guy though who needs to move inside to guard.
