What a nightmare of a topic to me. Very Bad memories.
Good draft picks can sustain a franchise, bad picks can crush a franchise pretty quickly. Obviously, free agents can make a difference.
My pick is Dan McGwire. He had good numbers against nobody in college, but he was slow as a Sloth. I knew Bubba Behring hand picked him. I can remember other high QB draft picks like Kelly Stouffer, Rick Meier all contributing to our offensive woes. We did have some great defensive and special teams players.
Lamar King, Chris Macintosh, etc
We lost the Brian Bosworth lottery, every team would have signed him, but the Seahawks had to pay him.
