In baseball terms, you don't want a power hitter that strikes out as your quarterback, you want a smart, all around guy that is consistant. A guy that hits over .300 and does it over and over and over again.
One stupid pass, one failed blitz pickup or one slump of throws kills a drive, has a sack/fumble or interception written all over it and turnovers kill.
My beef with a guy like Jake Plummer wasn't that he couldn't do anything good, it's just that he'd come out there and make one of the stupidest throws I'd ever see in my life time 1-2 times per game. When Mike Shannihan minnimzed that one year, Jake made the probowl. The other years he was jake the trash man plummer.
The problem is, Tavaras Jackson isn't even the power hitter that strikes out a lot, he's the guy that strikes out a lot that SOMETIMES hits home runs.
He doesn't have the mental capacity and experience to play QB, and everybody just tip toes around the issue.
