If I were a high recruit like Rowan or Heron.... THAT is what I would do. Otherwise, it is a long time before graduation and you have these recruiters from every Tom, Dick and Harry school showing up, kind of like flies buzzing around dog crap, and you are not ready to deal with it. But, if you commit then you can just say 'I have already committed to Pitt' and they are gone. Then, when you are nearing graduation and are ready to deal with it, time to open up your recruitment and go from there.
But, I do not see what good this did Dixon. Not sure he is any better off re these two then he would be if he hadn't made the early offer. We will have to see what happens.
Another thing here... is these are 2016 players. It is in 2017 that things really open up... losing Young, Artis, Jeter, Jones and Newkirk... almost our entire team... and THAT is the year we should be wanting to bring in top recruits. The thing is, an opening to start immediately is something that is most attractive to highly ranked recruits.
The last thing here, is on the ESPN Pitt recruitment page, it shows we have offered Miles Bridges, who is a 5 star SF from Flint, Mich, whereas Rowan and Heron are 'just' 4 star players. So, you never know what is gonna happen with recruitment. But, at this time, it is showing NOTHING for us and 2017 players.
