I wouldn't, but I don't think it would be an easy fight for Rock. It'd be grueling, but in the late rounds, Marciano's power and physical strength would take it's toll. I think Qawi finally gets stopped circa 11-13.
But qawi wasnt the kind of guy to fade late, and he was strong as an ox. Not impossible, but fae from a given imo
Yeah, I'd take Marciano, but it'd be a real war. Qawi's jab-and-roll style and his shortness is likely to give Marciano all sorts of headaches, but eventually, I think the intensity the rock fought at, and the physical imposition Rocco brought to the ring wears Qawi down and he gets stopped some point after ten. Although, I could possibly concede an argument that Qawi would win a ten-rounder. In all honesty, I think Moore was a good bit better than Qawi, and Marciano basically bashed fuck outta him. I think Qawi from L.Spinks/Holy I would beat Walcott, though.
