Remember it's not like it's completly Dana White (as everyone seems to think it always is). The UFC's decisions are made by the owners/Joe Silva/shareholders and other marketing people. i love how it's always "dana-this, and Dana-that". the guy does the speaking for the company as a whole.
Cutting guys is something every Sports team has to do...the UFC can't send people back to the minors so they let them go and another orginization picks them up. They put a couple of good fights together, and they may be welcomed back. You have to make room for the up and comers to the sport as well...if they cut every guy that had a loss from TUF there would be a ton of guys gone. Some of those guys have grown into solid fighters (Griffin,jardine,Bisping). While i do agree with some of the posters here, that Alexander and Sakara are not cutting it...you have to remember that every contract is different and every fighters career takes turns constantly.
Business is business...you would all do what's in the best interest of your company if it was your money and livelihood on the line.
Fighters I enjoy watching:
Quinton "Rampage" Jackson
Joe Rogan NutHugger...and proud of it
