Wanstedt, while conservative, has proven to be a VERY quality coach. Dude even won Coach of the Year with the Bears. Now here is the tricky part. He will NEVER be considered a candidate for Executive of the Year. He just doen't have the ability, for whatever reason, to be a top flight GM. That is where Spielman comes in, and while he isn't actually the GM, and doesn't have the final say, he really does all the work of the GM with Wanny. Without Spielman we'd be in trouble.
Wanny is a good coach, he just isn't a good GM.
