Truthfully, we don't have enough data to make a true assessment. In the absence of data, however, the burden of proof is on Ike as Tyson proved his ability. As such I have to pick Tyson by KO or clear decision (most likely KO as Ike seemed very hittable).
I think maybe it's a bit unfair for Ike. Truthfully I don't think he'd have a shot in Hell against 87 Tyson. In fact, pre-prison Tyson in general beats Ike. 97 Ike vs 96 Tyson is more debatable.
Too little dada to know for sure and thus Tyson should be picked by default, as DM pointed out. However Ike's win is possible. If his chin was on ATG level (and we didn't see proof otherwise), then his ability to keep up pace, strength and punch would be a formidable threat to prime Tyson
Tua hurt Ike. And mind you, we're talking about with pure power. Tua not in Tyson's class in terms of handspeed, precision, and combination punching.
No chance for Ike. Iron Mike simply had too much of EVERYTHING for him. Too fast, too powerful, too unpredictable, and Ike is too hittable and compared to Mike, SLOWWWWWW. Tyson early in no more than 4 rounds.
