We never saw the real player, injured and missed games at two different junctures. For that reason I thought he might return to have a better season and bump up his stock. I know it's all about potential with the NBA but you can't hurt yourself on draft night coming off a good season where your name was out there all throughout the year.
Regarding Roach, I'd take a senior guard of his quality over any freshmen coming in. No one anywhere thinks he's coming back though so maybe someone has heard something or maybe that's just assumed these days, we've been able to keep only a few good college players for three seasons here in the last five years. Wendell Moore and Jeremy Roach and that's about it. In chapel hill they stay six seasons lol.
Here's a thought- Do you think Tyrese Proctor based his decision on who was coming back to Duke in assessing the teams chances next year? surely he did, and of course would have looked at who is coming into the program. So could he know some things we don't yet on returnees?
