To me it looked more like Sylve had both hands on it and the receiver only had one hand on it until they landed and went out of bounds.........Having said that, simultaneous catch goes to the offense. (like tie goes to the runner). I don't think they caught it together. Sylve caught it first.
That should have been the case in 2011 in the 9-6 game against LSU when Michael Williams went up to make the catch at about the 10 yard line for us, but was ruled an INT. We all know how that turned out.
