This surprised me.

A Co-worker of mine brought in some sports book information about upcoming fights. As of right now Paq is a 2-1 underdog against Cotto. Vegas 99.9% of the time is spot on with all sports bets, over/unders, totals, spreads its just crazy but this one genuinely shocked me. I was expecting 1-1 or an edge of a MAX of 1.5-1 but this really caught me off guard. Granted these numbers are going to change but... should I put some money on this bet? I still feel Cotto is going to win which is why I'm sketchy on putting some money down. I learned the hard way from the DLH/PBF fight to wait till fight night... I put money on DLH the night before the fight, as he was the underdog. Come saturday PBF became a 2-1 underdog and I lost my $100 instead of making $200 plus my hundred back. Essentially I'm looking for some advice... should I go with my brain and see if Cotto becomes the underdog later, or bet now as I might not see 2-1 with this fight again?
