OK, knowing what I know now: I'm happy with Suh. The Lions' pass rush needs all the help it can get and collapsing the pocket from the middle can only help. Pouncey was a kind of BPA pick, as the Lions could really benefit from interior line help. I think he's too good to pass up and can play Guard.
Dixon was a "following on from Pouncey" pick. If he and Pouncey are as good as advertised, then they will help out the Offence and keep the D off the field for large spells.
Thurmond addresses need- a risky pick with lots of potential. Polk is a hard hitter, so my fantasy is to move him to SS on running downs.
In hindsight, I would have picked an OLB higher. With Sims gone, this is a real area of need for the Lions. I would actually use their 2nd or 3rd on this.
