If I remember correctly, and it was said a number of times a number of different ways, what he said was that CPJ built a line designed for a different offense, with different needs, requiring different skills, and that he needed to recruit a totally different kind of player. He needed kids that were 6’5” 320+ With long arms and reach, and that wasn’t the current makeup of the OL.
Now, I think he wasn’t tactful in how he approached it, but I think he and Key were communicating all the time with the OL and the players knew exactly where they stood.
Obviously, Kenny, Lay, Minihan, etc. we’re all CPJ OL who stayed and played for CGC and CBK, so there doesn’t seem to be too big an issue with these guys.
Personally, I think the disgruntled players were probably more on the defense, but that’s a guess.
