Redskins NFL draft: why pickup a quarterback?

All around DC the rumors of new quarterbacks coming to the redskins is getting ridiculous. First Cutler, now talking about trading up to get Sanchez. I believe if jason campbell struggles this season, we should give a shot to Colt Brennan or Todd Collins, who ever wins backup in the preseason. Its obvious that the front office doesn't believe in Campbell. Will Colt ever get a shot? Thoughts...
