Haye had one strategy. That is to lash out and try to land the hayemaker. It landed a few times but of those that did, didn't knock out Wlad or get him in bad of shape for Haye to get close and clean up.
The rest of the time he stayed away from danger. He took only a few big shots himself. Haye was not an experienced or scientic enough boxer to know how to get inside of the jab and work from that area. Definitely an anti-climatic outcome. Haye can't say anything now. He didn't deliver on the boasts.
