My problem with it being the NXT guys is that it combines two potentially great angles. If the NXT guys do their angle, and we get a good storyline out of the Undertaker attack, then the WWE will have two must-see angles going on at the same time, something that never happens anymore. Having the NXT guys be Undertaker's attacker would certainly improve the NXT storyline, but I don't see how it could improve it so much that it would be better than having a completely unique angle. What I'm trying to say, without being too wordy, is that in this case the sum is not as great as the two parts.
