Ring cutting doesn't really apply to Pac's ambush/swarming style... ring cutters generally are measured in their pace and aren't darting around. Ring cutting is a focus that works for guys who like to work on the ropes and keep their opponents on the ropes (Triple G, Mexican fighters). For the record, I think he had excellent success cutting off the ring on Algieri.
Pac can cut the ring off, Pac can punch for 12 rounds, Pac can use EPO again, and he's still going to get his ass beat lol... Pac ain't built like that. Bradley and Marquez who box showed you that. Now Pacs fighting the best boxer in the world lol. He's doomed!
