That's another thing that has changed greatly since Parcells' heyday....
QB's who come out early do poorly...those who stick in college for as much development and experience as possible seem to do better. Vince Young is finding success, but it has more to do with his raw athletic ability than reading defenses and delivering passes.
OL who come out as seniors seem to be graded pretty accurately these days. The great OT's and perennial all pros every year were almost all top draft picks, with few exceptions.
It's time for us to draft some blue-chip WR's and OLmen...enough with the defense. Especially now that we have a young QB, we need to surround him with guys who will grow and be with him for years...anyone who thinks Crayton and Hurd are our future starters are crazy.
If you ignore one side of the ball for too many drafts, you'll never have the type of impact players you need on both sides. People love the mantra "defense wins championships" but you don't see many teams with patchwork offensive lines, average RBs, and older receivers with no youth winning titles...very rare.
If your offense sustains drives and puts up lots of points, you defense only has to step up and get stops a few times a game to win. If all your focus is on defense, you better have a defense that dominates and stops the other team on most possessions.
