I think that Ireland did the right thing in regard to Matt Flynn, but he really missed one on the Odrick/Misi instead of Earl Thomas draft:
Here's a quote from SBnation's Seahawks FieldGulls Blog regarding Earl Thomas...
And, as expected, Earl Thomas flew around everywhere as the last line of defense, allowing Kam Chancellor to hurl himself around on underneath routes and in run support. In short, there's no reason to think this team won't field one of the five best defensive backfields in the NFL this season....

~A quick note on Thomas: I can't get over just how much ground that guy covers on every damn play. It was the very first thing I noticed when I attended his first ever preseason game last year, and his improved anticipation make that game speed even more staggering. He's the one guy on the Seahawks who can make a legitimate claim to being the very best at his position in the entire league.
