The P4 is always going to look for depth, especially experienced depth that has had some success. Kansas St. is not looking for Roberson to be a program changing starting QB, but to provide quality depth and he can do that. Starter gets injured and maybe Roberson gets his shot. I don't think Mora wanted Roberson to hit the portal, but he decided that he was down the depth chart and Roberson decided to move on. Here is the conundrum of the portal: Evers, with no experience but higher upside is not attractive for KSU which already has a bunch of inexperienced QBs, but Roberson with experience as a starting QB is more attractive.
