Scared??? 95% of the guys that fought Twist later in his 'roid?' days.
Milbury -Bridgman is the all time classic that I thought of .
How about fighting like they were scared??? Surprises..
Ray and Twist vs Kocur ?
I thought Probert looked (fought) with a worried look vs Twist (I think in STL ..he didn't look like he could stand up..not a good showing.
How about Fotiu at the beginning of the Wilson fight..he looked like a cornered animal.
Secord and Hoyda looked a little scared vs Gillies.
Possibly Bridgman looked worried about Jonathan.
Really, any of the big punchers Playfair, JK, TT, Semenko, Boogie , Orr had opponents looking 'nervous'...a lot had that look "Oh , I can't get hit by this guy clean" look.
Then again , there's the guys that should've been scared that weren't..and paid a horrible price :
