If you banged a chick frequently from 2005-08, and she was mediocre in bed to the point where you had to dump her, then why would you start doing her again in 2013 when the chick you were with left you for a better man? I hope that analogy works better than "he was a terrible on field manager in 2008 and no other team would touch him so why go back to him?".
Gibbons will never get another MLB job as a manager. Never. Ever. On any team. A bench coach? Possibly, but that's it. He's not coveted. Go elsewhere. Anywhere else. Try something new. The Jays got burned by Farrell and went right back to the chick who is always free on Friday night's and doesn't require dinner/drinks/dancing to give it up. OK, I need to stop this analogy before I picture Gibbons in a dress.
