5. The Hiring of Jim Mora
Jim L. Mora, Seattle's head coach for one brief year that wasn't brief enough, was a loose-lipped PR embarrassment before his Seattle tenure, a vacant, reactionary excuse-maker during his tenure, and a facepalm-inducing fop after he's left. He had never created anything but a mediocre defense before Ruskell tapped him to succeed Mike Holmgren as Seahawks head coach. You could rank his hiring anywhere on this list of Ruskell's greatest failures.
I don't know which is worse - that the players quit on Mora before the season was half over, or that he was trying to make grandiose, larger-than-life big-shot gestures before the season even began. T.J. Houshmandzadeh and the watch, really? Did you think we'd completely forgotten about the Huskies comments? Before he'd had any chance to (re)build credibility and trust with the Seahawks or their fans, he was already flexing for the Super Bowl pregame shows. Ugh.
From his thousand-yard-stare to his reflex of publicly hanging struggling players out to dry, Mora did one thing right: he taught us how much of the dignified, responsible, patient Mike Holmgren we'd taken for granted all those years. He also gave us a frame for new coach Pete Carroll, who defends his players as a coach should. It's pretty bad when your biggest accomplishment as an NFL head coach is to make both your predecessor and your successor look better than you.
