 I was thinking Rosen and Oz, but then I remember McCown. Oh, my gosh. I didn't think McCown played for the Niners. Rosen did. He was a backup, yeah. Now, I nailed it. His Bears tenure would last two seasons because of injury and inconsistent play, and he spent two injury-marred years with the Bears in his final two years as a backup for the Dolphins and a brief tenure with the 49ers.
