Just a case of shit happens.
Heads and Tails have equal odds and the odds have just been in Serras favour.
This sort of thing happened to Team No Love, Bj Penn's Team and Shamrock's Team. Hughes has been a coach on this show before, and is an accomplished fighter and historical Champion, he knows how to make fighters. period.
Shamrock ran his own gym for many years and trained some good guys, and is currently working as a coach in the IFL, he knows how to make fighters. period.
Bj I assume has his own gym(s) down in Hawaii, this man is such a good fighter it would be impossible not to learn from him.
Team No Love was a bunch of vets whom in turn had the aid of Randy Couture, GSP, Franklin, Liddell and to a lesser extent, Laimon. They are fighters who've been in this game before and know how to learn, teach and fight on their own. They have fellow Teammates in the same boat as them to push them on. Seasoned Vets on the same Team as you, if there is a bigger thing to pump your ass up then I haven't heard it.
Point I wanted to make is that your going to learn just as much as the other guys and that in the fights, shit does happen, fighters lose and teams lose, it happens.
But of course it doesnt hurt that Serra is a full time teacher himself.
