Not gonna lie, I was impressed by Glover in this fight.
He showed he still has durability, power, and good offensive grappling. He also showed good fight IQ. I can't really say that his takedowns looked great, so much as OSP's takedown defence looking terrible.
At 34, the question is how many good years a fighter can have left in him (especially since he has been fighting since 2002).
Glover clearly has some fight left in him.
OSP, on the other hand, showed so many technical problems that it is difficult to imagine him resolving them in time to make a serious run at the title.
