The best argument I think for Barkley remains that he's a once-in-a-generation talent and that the type of talent that was available QB wise comes along every year. The problem with that argument is that you're not always in a position to grab that QB talent and that even if you do, by the time that QB talent is developed and ready (I think QBs, with notable exceptions, take several years to be ready to win and running backs are usually done, with fewer notable exceptions in only a few years), Barkley would likely be on the downside and thus the benefits of having both might not be that great.
I think Herbert is as talented as anybody who came out last year, but he seems several years away from being an NFL QB.
