I still think the way the lions mismanage personnel is partially to blame for the way things fell apart with this guy. That's not an "Aw poor Young! He just needs heeeeelp!" remark from a bleeding heart. But these guys are young kids who've been given a lot of money and put on a big stage. If managed poorly these guys completely fall apart. Luckily it takes a lot of earned respect and proven ability to be on the staff of a team managing players in the NFL, they don't just hand those jobs out. If not, I'm sure we'd see so many more cases similar to this where these guys are out of control.
I happen to think the Lions just do a bad job of managing these guys. Young isn't the only case whatsoever on the lion's roster who's had issues. Look at last offseason, it seems like there were number of guys on their roster who acted out. Jim Schwartz claims to have a 'zero tolerance' policy, then goes right out and defends Suh whenever his complete disregard for character shows through. Inconsistency and mismanagement is no way to handle these guys.
I have questions about his usefulness to the seahawks becuase of 1.) his size - we don't need another baldwin/tate type body on the team and if we did we'd keep butler unless Young came in and was amazing and 2.) as someone said he's not a #1 guy.
But I'm also not against bringing him in for a look just because he has character issues. Sometimes guys need a change of scenery to establish a new perspective. And sometimes they will squander that chance, in which case you cut bait and move on, but you risk very little just taking a look.
