This pretty much sums him up. One other negative: He seems to coast for a long time, almost like Helenius, and then suddenly throw a barrage of monster shots. That will work against B-level fighters, but top opponents must be intimidated with REAL shots right from the beginning, unless you have Floyd-like defense. Thruman most definitely does NOT have Floyd-like defense. Still, that power & (occasional) aggression can't be denied. A good trainer could probably do wonders with Thurman.
I have to see him in with a technically proficient fighter before I make a ruling on him, but so far, so good.
