Like others, I imagine the OC. Especially given Rex's track record with developing (and picking) QBs.
After seeing all of them now in preseason, I'm not worried. They all have plusses and negatives, but are good enough to get us to the playoffs with our defense and playmakers. Convinced the OC, given his own track record, can build an offense around any of these guys. Despite popular opinion, I think that guy is going to be Manuel with Cassel as backup. Taylor is intriguing, but I don't see the OC taking a chance on him with the style of play that's proven time and time again to cause injuries. As we've heard, though, Rex is a fan, so we'll see who shakes out.
