I'm sure i've seen worse fights for being straight jabs a nothing else. At least Haye gave some ideas a try.
Those low lunges were bad, but I guess they worked once or twice. The fact they worked at all probably meant that became "Plan A" and perhaps shouldn't have been.
I was wondering about the lunges. Personally, I thought as he came in after the jab, Klitschko's left arm would drop down across him and then klitschko's elbow would come up as a reaction to Haye's lunge. Too tall for Haye to reach over the arm to get a good shot at the head most times, so he seemed to end up sliding up under Klischko's arm and either ended up getting held stood up around the neck, or ducking (to dodge a possible counter?) and ending up with Klitschko's arm on his back because he finished too low and off balance.
Once there I don't know what you'd do if you were Klitschko... maybe lean down and try to keep Haye there, because if you let him up he's within range to spark you, or let him go and risk it. It as probably easier for Haye to put his knee down once he was there than try to force his way up from being off balance... but maybe he should, then he would have been up close and could have done something, but he probably would have got held by Klitschko and then he'd be back to square one after separation. would have been interesting after one of those lunges if rather than go down and winge he popped off a massive uppercut.
