What is great about Junior's striking:
He's got a good jab. It's quick, intimidating (especially with MMA gloves), he can move with it.
It's used both with combinations in mind and as a defensive tool.
His straight right is fairly fast and precise. He throws it in combinations and as a single punch.
Both straights of that calibre -long, hard, fast, preciese- are rare in MMA.
Often, they go to the body as a single strike or as part of a combination. This reliably creates openings in his fights.
His overhead right is pure lightning.
The left hook, relatively rarely used by Junior, is dangerous. Mark Hunt can attest to that.
And he also likes the right uppercut.
tldr; the brazilian has not just heavy hands or decent boxing.
He creatively commands a proper ARSENAL of dangerous weaponry.
Now that he throws in takedowns and kicks, too, in there, there's little to stop him from taking that belt, once again.
The fan in me hopes that Overeem absolutely destroys his next two opponents.
I'd like to see him, a slow, aggressive (counter) puncher- and clinchfighter solve that puzzle.
p.s. my, that russian was DOMINANT!
