Yeah, we can't say that for sure. You just don't know. I remember one time thinking that getting the Twins, two top-10 recruits in one, was the biggest recruiting "get" under Cal. I remember thinking "These guys are prototypical, in-control pointguards, just what we need after Harrow". Not that they weren't great, but the college level is a big adjustment, and 99.9% of recruits can't quite replicate their highschool level of play. I think Davis is the only one that comes to mind, but he was made in the lab, so it doesn't count.
You seem to know your stuff... how do you envision those 3 playing along side each other? Ulis HAS to play the #1, can't play the #2, and will be needed for defensive specialty. Do Briscoe and Murray play ~10mpg at the #2 then (or rather, a 2-pg backcourt), filling the rest at the PG spot? Where does that leave Matthews?
