Cousins' comp right now is Carson Palmer. He puts up a good amount of stats and wins some games but ultimately gets overshadowed by truly elite QBs or teams that are just better than his. He's going to land easily inside the 20 of yards and TDs, but with minimal postseason success, he's fringe HOF at best. If he manages to hang around a few more years, he gets close to the Phillip Rivers/Matt Ryan tier, but again without some hardware or some playoff success, nothing about his career really stands out other than stats.
The list of USC QBs that are deemed the next big thing that never really do much beyond consistent starter is pretty good sized.
