To be fair to Spinks, he got dropped from an uppercut to the solarplexus (gotta hurt more than an uppercut in the armpit!) and got back up to FIGHT.
Alot gets said about Spinks taking his time coming into the ring and all the speculation around that but I mean really and truly, once Sinks was in the ring, he was game... Fair play to him. So no, I don't really think Spinks being supposedly scared of Tyson has anything to do with Foreman because
A) Tyson was freakishly fast & ferocious
B) Foreman would of been slower and simpler... In comparison to an old Larry Holmes, let alone Iron Mike.
C) Spinks didn't set out to fight Tyson any differently to any other Heavyweight.

Also, wtf has Tysons 'fear' of Foreman got to do with anything? When was the last time you saw Michael Spinks fighting out of a peak-a-boo stance, making wide side-to-side head movement and working to get inside for 100% of the fight?
All things are relative, Tyson comes to you, spinks moves.
The amount of times I see that old 'fighter A, B, C' verse thrown around yet here we are again...

And yes Michael Spinks was a GREAT Lightheavyweight
