What has PT done when he gets 15+ carries in a game, and he becomes the "feature" back? Go back and look.

It's really pointless for me to argue against the PT naysayers, you've already made up your mind and he can do nothing more to sell you. I don't doubt Wells can be a solid NFL running back, but when SP has made a commitment to run the ball with PT, we have all we need at that position, and the 14th pick can be better addressed.
