I really don't know for sure either. Do you recall that on one of these topics we went over the "spotlighters" thing ?
Some wrestlers actually thrive when in the spotlight. Limelight, if you will. Conversely, others will actually freeze in the moment.
Which is why a wrestle off in the room or within the squad isn't always so definitive. We've all seen great room wrestlers who are capable of hanging with or beating anyone in practice or a wrestle off, yet freeze up and are ineffective in real matches, and vice versa.
