Same thing I told one of the pro fighters I train with after he lost a fight he could've won: don't approach the positional aspect of MMA indifferently. He had significantly better BJJ than his opponent, and they were comparable standing, but instead of attacking with his ground game he didn't try a single takedown and tied his opponent up in closed guard when he was taken down (to get it stood back up) instead of attacking with subs and sweeps, and ended up losing the fight, waiting for an opportunity in the striking that never came.
We were in awe of Fedor hanging out in Nog's guard for an hour and standing with strikers, but that is really a horrid strategy when you're well-rounded and dangerous from every position. Play the percentages. If you have the abililty to, go where the difference in skill is the most favorable for you. Don't jump into the guard of a BJJ master. Don't stand with elite strikers. That's the whole damn point of being well-rounded in MMA. There will always be a specialist who can do his thing better than you when you have a broad skillset.
