Peak Bob Foster (1968-1972) would have at least decisioned Dwight Qawi over 15 rounds, but he was also capable of hooking off an uppercut, as he did against Dick Tiger. A short, fire plug of a guy that Qawi was, although a very good fire plug, would have been a likely ko victim of Foster. Foster was scary at his peak. He resembled a big praying mantis in there against those poor guys. The way he went after and then executed Vincente Rondon was awesome to behold. You actually felt sorry for his opponents. It was like watching an outer space alien, a "terminator" going after them.
As long as Qawi kept his head down and chin tucked in he'd survive. But if he got sloppy Foster would set him up with uppercuts followed by hooks. Qawi was a tough SOB and amazingly effective at getting inside the reach of taller fighters. But he didn't have punching power to compare with his durability.
I always though Qawi was an expert at taking people's jabs away. Countering over the top with that right. If he could take away Fosters jab then Foster would be in for a bit of trouble.
Standing precisely at 56½, with no amateur career and most of his fighting experience taking place on the streets and inside Rahway State Prison, Qawis short reign of terror at light heavyweight is remarkable. From out muscling James Scott and sparking Mike Rossman with a single left hook, to battering Matthew Saad Muhammad for the title, Qawi was tearing through opponents left and right with one objective in mind: To hit very hard, and be hard to hit. Winning the title may have been too much, too fast for someone such as Dwight who had been surrounded by poverty and violence for a large part of his life; perhaps he simply just became overconfident, but there was a noticeable difference in Qawis style by the Eddie Davis title defense in particular. His work to the body became less consistent and was instead replaced by an increasing urge to load up on his punches. I think it was Michael Spinks who said ringside at the Davis fight that this is not the same Braxton. Regardless, Qawi circa 1981 would be applying pressure, showing angles, and trying to slip his way to the inside where the real damage was done, courtesy of those short hooks and uppercuts to the midsection. Dwights slight head movements and various blocking techniques would allow him to last the distance, but ultimately Foster was simply too big and too powerful. Hed keep Qawi at a safe distance with the jab for much of the fight and in a defensive shell once Dwight realizes he wont be able to counter Fosters thunderous shots in the same manner he did Saads. In other words, see the Spinks fight.
Spinks hit arguably as hard. He was knocking guys stiff when he opened up. If there's a difference in power, it's minute.
