Not buying the Cards / Murray hype. College success aside - he's a rookie starting for a team that was terrible last year. Their best player is on the wrong side of 30 and their coach runs a gimmick college offense (Chip Kelly anyone) and barely had a .500 record...in college. That's not good.
He may develop and be very good. Will be interesting to see. I'm just not big on the 'this time it's different' idea. One year of D-1 college and he's the greatest in a generation? Apparently he wasn't as good as Baker Mayfield - otherwise he'd have played more than one year.
