6'1 or 6'0 not much different, Bruschi is right in that range. The majority of it is a mentality, very hard to teach. I said 6'1 because any shorter it is difficult to create the necessary leverage. Parcells said that if you start making exceptions pretty soon your whole roster is exceptions. Maybe a vet like Fletcher-Baker can prove me wrong but as far as draft picks I would prefer they fit the mold otherwise their jobs become even more difficult.
