Have you watched him and and have you watched how we use our RBs? Barkley may be the most talented athlete in this draft, but he's not the best RB and his playing style definitely does not translate to how we use our RBs.
This article does an awesome job breaking down some of the top RBs in this draft. http://www.profootballweekly.com/2018/02/14/pfw-nfl-draft-newsletter-sample-mosher-charts-the-top-rbs/a6fjmrs/#//
I'm totally against taking a RB at 7, but if we did take one, it needs to be Derrius Guice, not Barkley. Guice's game translates much better to the NFL and is much more in line with how we use our RBs. Dude is going to lead all rookies in rushing and probably be top 10 in the league in rushing next yr.
But if you think Barkley is the better pick FOR US, I'd love to hear why.
