Depends on the OL. But that's true of any other position. Some good QB's come in too raw to contribute then become really good by year 3.Well, maybe Jones read it in a magazine article (ha!). However, Fulmer has said the same.
I hope you're right, though.
To the extent it is true... it is true of any position. But now more than ever OL's are coming in ready to play within the first couple of years. The question in my mind concerning the current OL is how much was talent and how much was development.
PS- Fulmer started young OL's also.
