Brossette's been doing very well at the camps down here. Supposedly looks a bit faster, though still not anywhere near Fournette. Factor in the fairly low level of competition when watching his tape (red helmets with a blue "e" are Evangel, which is a talented team; white helmets with red and blue stripes and "JC" on them are Curtis, which is a very talented team; both are teams University Lab plays that would be good gauges of his speed).
He's made a few statements about being wide open in his recruitment, so that's somewhat encouraging, if a bit boilerplate. His star blocker, Garrett Brumfield, is an LSU commit this year. According to Brumfield's father, Brossette really is weighing all of his options (in response to constant commentary from LSU fans about him being a done deal), and he's enjoying the process. Also said that Brumfield strongly believes that every recruit should be left to make his own decisions, so he won't be leaning on Brossette to follow him.
That being said, I'd be very, very surprised if he left Louisiana. Baton Rouge kids are just so overwhelmingly unlikely to slip away from LSU. I'm sure there've been kids from Catholic or University Lab that've escaped, but I just can't remember any.
On a side note: It seems I was mistaken a few months ago when I said I didn't know much about University Lab. Apparently my sister went there for a year after Katrina destroyed her high school (she called it "U-High," and somehow I never put together that U-High = University Lab). It's a very good school. I could see a typical U-High grad looking at the Notre Dames and Stanfords of the world as ideal destinations.
