He looked good of course. I personally think he has the tools to make some major noise...nice, crisp punches and fast hands.
He seems to have become a slow starter, judging from his few fights. He looked better than he did for quite a while though, I liked it.
Did you see his fight against Maddalone? I'm from Germany and have seen a couple of Boytsov's fights. He's a bit above the average, with impressive power indeed, but a huge lack of flexibility, a small and square fighter with bad movement at all - easy to predictable for the taller guys, and easy to hit for the faster ones, of course. That sounds not very good to me. (Maddalone landed some good, hard hands by the way - and he is not that special fighter...)
