I haven't seen anyone come in with a gameplan to straight up grapplef him. It's been overly pacing or brawling. Izzy is the best striker in the UFC, yet all choose to stand with him.
His bottom game is completely untested in difficult situations. His TDD hasn't been tested much. Maybe tried 1 or 2 subs that weren't close.
I'd hope some of these dudes at least try. He's the new Spider without Sonnen, Leites or Lutter, but with guys who can do a lot of things, yet choose to brawl with him or just wait not to gas. Some horrible gameplans.
So Izzy being a good defensive grappler has become quite the myth on these boards.
Glover has a tendency to stand. If things don't go his way or he sees an opportunity for a TD he changes completely to grappling with the goal to end the fight on the ground in that sequence. Israel hasn't seen none of that. But because of Glover's approach to stand up first he could get pieced up like the rest.
