#4 The culmination of a massive feud between Drew McIntyre and Bobby Lashley
Even though Drew McIntyre and Bobby Lashley haven't fought as many times as people believe, the fact that this feud has continued for so long has irked many a fan. So the best way to bring the Championship feud to a fitting conclusion is through a massive Hell in a Cell match.
One has to imagine that irrespective of the result, Drew McIntyre and Bobby Lashley will go their own way following this match. The WWE Universe may not be too enthused about extending this feud.
#3 The storyline reason, of course
Drew McIntyre does not want Bobby Lashley's manager, MVP, to interfere in the proceedings. The best way to ensure that is by battling inside Hell in a Cell. However, we've seen through the years that if someone wants to enter the Cell, they often do.
Could Brock Lesnar make a grand return and enter the Cell after destroying the door? Could Kofi Kingston tap into his dark side, turn heel and attack Drew McIntyre?
