From the looks of it (based on screenshots and Kev's demo vids), they are pretty bad. They look like the ones nobody wears anymore (see Beanie Wells in the demo). However, I know I will end up editing a ton of guys to have them wearing the facemask Tebow wears. Unfortunately, the most common rev facemask worn didn't make it in the game. You know the one I am talking about (nearly half of UF's skill positions wear it).
BTW, thanks for uploading the vids of the demo Kevin. We appreciate it. The game looks great. Can't wait to play later.
