I can understand players WANTING to make the Hall of Fame, but my personal belief is that it should be up to the HOF voters to decide that. Larkin's job is to do the best he can do, and if his performance career-wise warrants a vote into the HOF, that is great news. If not, at least he had a great career and I'm sure achieved many of his personal goals.
To me, tacking on 25 games for the sole reason of getting HOF status is the same as sitting out a bunch of games in order to preserve a high batting average, swinging for the fences on every single pitch in order to break a homerun record, moping all over the mound in order to throw off the timing of the hitter or to preserve energy.
Barry needs to just step away from the game, and enjoy life. He's still healthy. Any one injury could change all that. He'll have no problem at all finding work elsewhere in baseball. Just not as a player. His time has come.
I do think that a very small part of the front office's decsion to bench Larkin is due to the mistake they made in signing him to such a large contract at such a late point in his career, realizing that they should have all along put more effort into developing or acquiring someone to take Larkin's spot.
Stepping aside from my allegiance to the Reds, I can see how in some ways Barry might not make the HOF. Sadly, he played in between eras, between the wizard of Oz, and the power hitting shortstops that we see today. That isn't his fault, but there is no guarantee that HOF voters will see it the way we do. All they will see is the numbers.
Good luck, Barry, in all that you do in the future!
