It probably means nothing, as recruits can be all over the place on Twitter, but if you look at the tweets Rowsey has favorited lately, practically ALL of them are from UC fans. I don't endorse tweeting at recruits, but it's interesting to see that he basically hasn't favorited any Marquette fans, even though they're tweeting him too.

Another interesting thing is that I was on a MU fan board and they were not hyping Rowsey at all. They were talking like "it might be worth a shot" and "good back up plan". By NO means did I get the impression was anyone thinking it should be a high priority to land him. It was more like "I guess we'll take him if that's all we have at this point".
Not the feeling I get on this board at all
