Scott,
Recent reports suggest WWE is optimistic about Brock signing an extension. JR commented on this as well speculating that future health concerns from UFC may be included in Lesnars thought process. If indeed that is the case then wouldn't Lesnar jobbing at mania be a colossal waste of $ unless they are planning a double turn. Is there money in Lesnar going over and Reigns learning from this and coming back stronger next year ala Shawn Michaels wrestlemania 11 & 12?
I think that recent history has taught us that there is no money in Reigns and even less in Brock given his costs. I would be gobsmacked if Brock ends up anywhere other than UFC.
