The problem with this is that the time and place that Rollins chose to attack KO just didn't make sense. It did not play as if he were just trying to attack Owens. It played as if he was trying to help Roman. I mean, scaling a cage to take on both Jericho and Owens isn't exactly the smartest strategy.
If Rollins only cared about hurting Owens, he could have interfered in the actual match. There was plenty that he could have done. However, he waited until it was a two on one beat down of Roman Reigns before he did a thing.
When it happened, I immediately commented that it made no sense. Sure, they are probably moving towards a Shield reunion at some point. But at that exact moment, and verified by that tweet, Rollins interfering was just awkward and seemed more like it was about helping Roman than hurting KO. I am sure their intention was hurting KO, but the very fact that we are discussing whether or not this was the case reveals that they didn't do it well.
