So it isn't "hey to many WR's maybe RSJ will change" but the other way around! They took other WR because RSJ isn't going to A&M.
I think there are different motives at play than this. They're recruiting like an SEC team now. Take all the best players you can, more good WR > fewer good WRs.
And also, he's from Georgia and was committed to Auburn at one point. If A&M signs him, it means one of the teams they play against can't.
I don't think this has any effect on RSJ, nor is it a sign that he isn't going there. He may not go there, but this isn't telling us that.
