WWEs decision to put the World Heavyweight Championship on Brock Lesnar was certainly an interesting one, but its one that may not have paid off either creatively or financially. Lesnar hasnt been seen since Septembers Night of Champions pay-per-view, and WWE kept ticking along without him. In terms of pay-per-view buy rates, Lesnar hasnt had the significant effect that WWE may have expected and his first and only title defense at Night of Champions only drew 48,000 buys compared to 2013s 175,000. A lot of that is down to the WWE Network, but the drop-off between the two events is much worse than the difference between any other non-Lesnar pay-per-view this year and its 2013 counterpart. In the past few months, rumours have resurfaced that Lesnar is not going to renew his contract with WWE after next years WrestleMania XXXI. The likes of Jim Ross, Dana White and even Paul Heyman have stoked the fires of a possible UFC return in Lesnars future, and if hes healthy enough he could make much more of an impact in the Octagon than he has in the squared circle. Time will tell where Brock Lesnars career will go, and he isnt expected back on WWE TV until around Royal Rumble time. From WWEs perspective, it might be best to not give Lesnar a choice by cutting their losses and not re-upping on their deal for another year of sporadic appearances.
