Let's take a look at the two fights in question - if they were included from the beginning, would it really have made a difference?
First we got the Fedor card, an unexciting and very predictable card - all favorites delivered, there were no upsets. Aleksander Emelianenko was picked by EVERYBODY. when there was a last minute change and he was replaced by gary goodridge (oh brother) only 3 people outta 8 picked up on it. 2 outta those 3 picked Buentello. With Buentello winning 4 outta his last 5 fights and coming in preparing for Aleksander (who is no joke) he was of course the CLEAR favorite here - with Goodridge taking THIS fight on short notice, being 42 years old and having lost 2 fights in a row prior to it the chance that people would bet on him where slim at best - the chance that me and geo BOTH would've picked him were ZERO.
In other words - CB would'nt have won, no matter what.
For the Silva-Sandman card it was about the Tim Credeur Vs. Cale Yarbrough that was added. It was unexpected and late, and UFC Fight Nights NORM is 9 fights per card, this card already had 10.
Out of the 9 people betting on it, only 2 people included this fight. BOTH picked Tim Creduer (100%) Yarbrough won a controversial decision over Schultz on TUF, he got TKOED in the first round by CB Dollaway, and his MMA record was ZERO FIGHTS!
Tim was the clear favorite coming into this fight, a veteran since 2001 with a fight record of 10-2 finished Yarbrough easily by TKO in less than 2 minutes of the first round.
In other words - people would've picked him and CB would've have won that either, no matter what.
