I think the questions about inside running are valid. He's not the most decisive back in the class. He's not the best inside runner.
But yes, he's the best prospect in the class. Probably overall, the best prospect (that guard from Michigan might have an argument). I couldn't rank him 3rd, and anyone who does is out on a ledge, for sure.
Being concerned about inside running is a big deal, because we know RBs in the NFL have to be able to run up the gut. Backs cannot live on the edge, you don't get the outside run consistently. You DO see bad decisions in the hole by Barkley.
Do I think it's enough to knock him down? Naaaaaaah. Barkley could wind up in a ZBS, where he doesn't need to get the ball and pick a hole, it's predetermined for him. Terrell Davis ran to the Hall of Fame this way.
Plus, his receiving skills are so insane, he can be a bad inside runner and still be the #1 overall back. 1,000 yards receiving seem very possible to me.
