Since WE Battleground constitutes as a pay-per-view, returns from high-profile WWE superstars are deemed necessary. The WWE Twitter account is already tinkering around with teasers of a possible Undertaker return, so one can only dream right?
With WWE airing the second of three pay-per-views in a one month span, the most low-profile pay-per-view events of the trio will benefit from a boost in star power.
WWE Battleground currently offers nothing in star power, so perhaps a return or two could at least help boost pay-per-view buys ahead of WWE's first-time offering.
Potential returns will be graded on popularity with fans and how well these returns could fit in with ongoing angles.
