Freddie Roach and Alex Ariza had ringside seats for the non-show put on last night by Shane Mosley in his wide decision loss to their fighter, Manny Pacquiao. After the fight, both said they think that Mosley, now 39, should retire from the sport. BoxingScene.com's Ronnie Nathanielsz spoke with the trainer, Roach, and strength and conditioning guru Ariza.

Roach had this to say:

"I don’t think he tried to win the fight. I think he just tried to survive and when you get to that point in boxing, I think its time to retire."

Ariza was more harsh:

"He didn't try to win. That's the whole f---ing purpose and if you don't try to win you're finished."

Ariza also noted that Pacquiao wasn't cramping, it was just "stiffness," and he was upset about the way Pacquiao -- in Ariza's expert view -- overtrained.

You might argue with the way Ariza chose to put it, as Shane Mosley at the end of the day is still Shane Mosley and Alex Ariza is a conditioning coach, and you might note that Freddie Roach said the same thing but didn't sound like he was trying to be such a big shot, but I do think they're both correct. I don't like to jump on the "retire, already!" train the way some do, and I don't think everyone should retire all the time when they lose a fight, but from where I sit, this is a clear case. Shane Mosley has nothing more to prove and he just can't cut it physically with the top fighters anymore. I don't need to watch any more Shane Mosley fights except the great fights in my collection.
