Gibbons doesn't know what defense is. He never has. Just puts what he perceives as the best offensive unit out there and hopes for the best (Francisco at third, Glaus at short, Edwin in left, etc, etc, etc, etc, etc). It's spanned a damn decade and he still does it.
Much like the Royals did with Ned Yost, the Jays have to "dummy proof" the team in order to get by with Gibbons as manager. Meaning, get rid of Navarro and LOLabello and call up Thole and Pompey. In that scenario, he'll have no choice but to use Thole strictly with the Dickster and Pompey everyday in left. Get rid of the replacement level vets that Gibby loves so much and he'll be forced to use what's left. That's the only way.
