Comparatively fresh? Edge had just been murdered by falling off a ladder through a table and into a baricade. Flair was healthy in comparison.
Age multiplies the effect of huge bumps in the mark mind, and Flair had already been suplexed off a ladder, hit with a chair an assload of times, bled well before the halfway point, and was the recipient of the murder/suicide Edge did through the table. In my mind (and it was a markish mind since this match actually got me pretty hype) Flair was much more worse off than Edge was. And he had a concussion they mentioned multiple times during the night! I just remembered that. C'mon, like I said, he was a corpse by that point, Edge was just a wrestler that had taken an extremely severe beating. Look how he was able to pop up, spear Flair and beat him down right after the match.
