This technique isn't used a lot, but Andrei Arlovski proved this week-end it was really useful, both as a protective/defensive move, and as a great counter.
I can't remember a lot of fights where a fighter used it. But in some key moments, we have Chris Weidman against Silva I.
When he threw a jab and Silva faked being hurt, he then threw a left hook and overengaged in a cross. When he came back with a backhand, it forced Silva to move back (and he couldn't counter), aligning his foot and that was the beginning of the end. Thank to that backhand, Silva couldn't avoid the left hook that followed:
This week-end, I think Andrei used it 3 or 4 times. And he caught Travis twice:
First, Travis overengaged in his cross, his head is too advanced, all his weight is on his lead leg, Arlovski misses his counter cross, so they are kind of back to back. While Travis tries to counter with a hook (bad choice when the opponent is on the outside), Arlovski uses that backhand perfectly and catches Travis:
Later, same thing. This time, Arlovski overengages in an overhand. Fortunately, instead of avoiding the punch by going back a little and counter with something, Travis tries to anticipate it and he misses too. Once again, Arlovski regains his posture while throwing that backhand that lands and knocks Travis down:
I liked it a lot. I think we will see more of these in the upcoming fights.
