I probably won't bet this fight because I have no idea who will win.  Anderson Silva is clearly the better and more established fighter, but he's old...  Jake has age and likely supplements on his side, so for me this is a risky fight for Anderson Silva while also being one hell of a payday.  I can see why he didn't want to turn this fight down.  Win or lose I suspect it'll be the last time he enters the ring.  Personally, I'd like to see Jake get knocked out and I'd hate to see Anderson Silva get knocked out, so I probably have too much emotion on the line to add money to it.  I'll watch the fight though and hope for the best.  Old man power better be on display.
