Word out of camp is that Jake has looked very good and adapting to the new offense very well (the new offense installed has been very well received and word has it that the offensive line loves the new scheme and Jake likes all his new toys (ie. throwing to the TE and RB's more)). Carr has been very erratic, but it's a very different offense than what he's used to.
From one of the Panthers board regular posters:
We needed the boost. From what I saw Thursday, and that was very vanilla and limited, it looks as if Colbert is right. I saw Carter catching passes over the middle, secondary receivers, such as TE, FB, ad RB are in on the passing game. Smith was Smith, but Defenses won't be able to double and triple him all the time. Look for King and Roserio to have good years. Gaines even caught a few balls. The zone scheme featured student body left and right with the RB finding a seam. Of course, there were other plays and schemes, but I think Foster will benefit from this and WIlliams will be better. I was very impressed with DelHomme. He seemed to be having a ball and was very effective. Carr has a ways to go, but a new system takes a while. From what i saw, he won't be sitting Jake down anytime soon.
