Found this when looking at the scouting report on Martin from Russ Lande of The National Football Post. I guess we should soon find out.
Some scouts will knock Martin and say he has short arms, but I was at the Notre Dame Pro Day last spring, and the scout who was doing the hand and arm measurements was not doing it correctly. If I recall, they measured his arms at just over 32”. When he goes to the Combine, they will be longer.
