Jimmy Smith had has flashes though that showed that he could be a really good CB in this league. And he has been since about 2013. He's overrated by a certain member on this forum, but has been one of the most criminally underrated defensive players in the league for about five years now, only started getting some recognition from other fanbases last season, which is utter bullshit.
Young had a few bad plays against Dez Bryant... But make no mistakes. That dude is skilled in coverage. As a rookie he was bound to fuck up at some point, and even then was capable of holding his own vs some of the better WRs in the league. It's actually a terrifying proposition that Humphrey and Young are going to man the corner positions for likely to next half decade at least because Young as a rookie looked the part of a well above average CB at the NFL level. He might be better suited for the slot, but underestimating his skill on the outside is dumb. He can play there. And adding Averett makes me really excited because I see a lot of that kind of potential in him too. Having him and Young switch off is going to be fun for the next few years
