Interesting fight. DC by decision or Glover by TKO, though DC has looked tough to finish even when he gets dropped badly. Glover plods and throws basic combos. He doesn't look too fast, but his hooks and back control to RNC have proved pretty effective most of the time. DC might try to stick and move, then lunge in with a hook, grab the clinch, land uppercuts, and tire Glover out against the cage by making him work for position (especially trying to tire out his arms to take away some punching power). But, DC could get clipped coming in.
I'd say DC by decision most likely, though Glover could make it an ugly fight for DC, and DC making it an ugly fight by wall-n-stall to a rather boring fight punctuated by flashes of Glover catching DC but not putting him away.
