Sillakh is actually the worst possible opponent for Kovalev (bad style matchup, high-risk, not much to gain since Sillakh is underrated now).

Sillakh is a highly-skilled, slick boxer with one punch KO power. He's been underrated since the loss to Grachev, who he had been easily outboxing during the fight until the stoppage.

However, Kovalev is a beast and I'm still picking him to win on Saturday. Sillakh was stopped in the amateurs by Beterbiev and others, so if Kovalev can find his chin without being KOed in the process, he'll win.
