It seems Weis made a conscience effort to try to get Tate all over the field and get him the ball in open space. As Tate has been progressing as a WR, he's showing that he is dangerous catching the ball anywhere on the field. This will make things easier for everyone else because he is certainly being double covered and in the case of Rudolph's long completion down the middle, he took three defenders with him.
In my opinion losing Floyd for the season may end up being a blessing in disguise, because with Floyd and Tate opposite each other the Irish would've just thrown the ball deep and against the lesser teams you can be one dimensional and win games, but as the case in the two BCS games, good teams can take away what you do best and you have to rely on other means to move the ball. If Floyd doesn't get hurt, I don't see Weis moving Tate all over the field, rb's catching balls down field or the Wildcat being used as much.
