What do you make of this sparring session between Filip Hrgovic and Deontay Wilder?

A little context; this was filmed in September 2013, in a David Haye training camp, during the time he was due to fight Tyson Fury. So let's paint the scene a little better: Wilder was 27 years old, 29-0 (29 KO), his best wins being Audley Harrison and Siarhei Liakhovich. Wilder was little known outside of hardcore Boxing circles. He was a sparring partner for Haye, giving him the chance to see how a multi-time World champion trains. Valuable experience for Deontay. I noticed in the comments on the vid people saying Wilder was taking it easy etc, but he most certainly wasn't. He had just as much to prove as anyone at this point in time. Hrgovic was 21 years old, still an Amateur, but doing well in the AIBA World Series of Boxing (basically semi-pro type matches). Hrgovic was very raw but already showing talent at such a young age. He had won the World Youth Championships in 2010, beating Tony Yoka to win Gold. It has always been said that Hrgovic's style would be better suited to the Pros. He gave Haye a pretty gnarly cut in the last round of sparring during the camp, which led to the Fury fight being postponed (Article). So how do you feel about this sparring session? Any articles or accounts online of the spar say that Wilder did go all out and tried to take Hrgovic's head off, but Filip remained composed and maintained pressure throughout, having his own success once Wilder calmed down. They were both giving it a proper effort, and to me I'd say Hrgovic got the better of it from the video. A little embarrassing for Deontay, his flaws are clearly there even against a pretty green Amateur who'd been boxing less than 3 years...
