Hell's Bells Coming To An End?

Trevor Hoffman gave up 3 runs in the 10th inning last night as the Diamondbacks defeated the Brewers 7-4.
Hoffman is now 2-5 on the season with a bloated 6.81 ERA. He has collected just 6 saves.
One of the all-time great closers will be 43 in October and it probably is time for him to shut it down.
However, who am I to say he should retire?
If I was a Major League player, I would play until they tore the uniform off me. Once you retire, that is it. Hoffman is making 7.5 million dollars this season. I don't think he can make that kind of money doing something else. Why not ride it out as long as possible.
Still, the way Hoffman has pitched this year, he might not have a say in whether or not he comes back.
He's one of the good guys in the game. I remember after he blew game #163 at Coors Field in 2007 that sent the Rockies to the post-season and the Padres home, Hoffman, as always, was gracious in dealing with the media. He's always been a standup guy, win or lose. A true class act. But right now, it's hard to watch him struggle like this.
