So I'm assuming you're not a fan of the Marcus Stroud trade.
There's a difference between the Redskins approach, cramming a bunch of random, overpaid veterans onto a roster, tossing them into a blender and hoping against hope something tasty is the result...and already having a core group of young talent that will have a large window, and adding a couple of strong veteran pieces here and there to fill in the gaps.
Tony Gonzalez is a gamer, having appeared in 156 of the Chiefs 158 games since being drafted. He's a great locker room, high-character guy, and perhaps best of all, the number one thing on his mind right now is WINNING. He's still close to his prime, as evidenced by his 99 catch, 1172 yard season just last year.
He is everything you look for in a guy to fill that veteran-amongst-a-bunch-of-youngsters type of roll. Three years of his services seem well worth an anonymous 2nd round rookie to me.
We've already set ourselves up beautifully for the future. This was a chance to improve our standing for the right now.
