Spinks destroys the grossly overrated 175lbs Moorer inside 10. It would be more competitive at Heavyweight, but I still take The Jinx to have enough to edge the decision 9-6; Spinks WU15.
A peak Moorer is under rated but Spinks is a little too tricky. Both of them at their best Spinks edges it out.
Spinks would get to Moorer's chin at 175 and take him out. Spinks has the better chin and skills here.
After watching Moorer get outboxed for most of his fight with Leslie Stewart, I'd have to pick the more talented and harder hitting Michael Spinks. Moorer was a deadly left hooker, and make no mistake about it, could deck Spinks if he was complacent or cocky, but 9 times out of 10, I'll go with the Jinx.
At 175: No point in scheduling 15 or even 12, cuz it aint goin' 8, and it does not end well for Moorer! I used to just love watching Spinks!! At HW it might be more competetive, but I'll still take Micheal Spinks.
