Interesting topic.
The point is, the entire battle was a blunder by Mace and the jedi. They encircled the arena instead of concentrating their forces (even with a flanking maneuver) on a focal point, and it ended up in them being in the center of the kill zone.
Honestly, there is nothing to indicate that the PT jedi were that good or really that bad in the situation, since they did a major F-up and the battle was a disaster. However, it should be noted that those who survived were the creme de la creme of the jedi order, and went on to be generals in the following Clone Wars battles.
And Glentract, that statement was a bit foolish; of course there are no ancient jedi standing. They're dead.
