simple.
coaches can preach/prepare gameplans all day long and would even work and have victories but if you dont have the right players with physical talent and the smarts and more importantly buying into the system then none of it will work.
i think we all have the understanding now that it truly was/is tom brady that held the glue together and he proved it by going to tampa and winning another championship with new coaches/new players at 45 years old while bill and the pats have struggled ever since
these coaches needed bill, bill needed tom. its no different then all the jackson brothers/sisters/nephews thinking they had real talent like michael haha
he will make in 2.5 games what i make in 12 months
