I loved the video, it was funny. He was emulating the comic book character who has the superpower to run through real walls, but since he can't do that, he ran through a sheetrock wall, and yes, the vast majority of us realized it wasn't hard to do, but that never prevented it from being funny. :D
Look a little deeper into that subject and you'll find his interview where he clearly states that the guys were being asked to demolish the place so they had a little fun with it. He also mentions how it was/is very easy to break through, and everyone was punching holes in it and I think even the G we looked at as an undrafted free agent (also from the University of Hawaii, Tala Esera I think was his name) put his head through the wall. Mauia never tried to fool anyone into thinking it was some awe-inspiring display of unique power ... it was simply a humerous depiction of the comic book character that we don't have the opportunity to see every day.
I for one thought it was quite funny. I just wish his play on the field were as entertaining as his videos. I also wish his behavior off the field were smarter. The word is that he's actually got very good hands, but one was injured last season and he couldn't catch jack. He definitely needs to stop getting into bar fights. If this were Cam's team he'd be gone, but seeing as it's Parcells' team, he's probably not going to be cut. But mediocre FB's are fairly easy to replace.
