Let me play devil's advocate here for a momemt...
Im surprised nobody has mentioned this yet.
Football requires the most thumb action because of how the ball is widely gripped ...Now Drew will have to retrain his surgically repaired thumb to not only grip and throw a football but with his feel and touch and GOAT accuracy. Not to mention taking hard snap from under center and to perform play action with the ball.
Will all this magically occur in that 6-8 week window along with Drew's hallmark quick release and accuracy?
If anybody can and will I think it is Drew Bress. ???
However, it may take even longer since this surgery has never been done with a NFL QB.
