According to FightMetric, GSP had a full mount and got Alves's back twice, excluding failed attempts. He also threw about three times the amount of strikes on the ground than Fitch did, counting only the first 3 rounds.
What fight metric links are you even using for this?
Either
A. You and I have totally different FightMetric sources.
OR
B. You're counting the Mount and Back Mount GSP had on Alves during round 4.
I'll grant that GSP threw more strikes.. He threw 150 over 5 rounds, Fitch threw 70 over 3 rounds. Neither of them even came close to finishing Alves through strikes so it really doesn't matter (for the purposes of this discussion) who threw more punches that were nowhere near finishing the fight.
As for why I didn't watch the GSP vs Hardy fight.. When I considered that Marcus Davis (of all people) had mount on Hardy in under 30 seconds of taking him down (and then Back Mount a minute later) I completely lost interest in that fight.
