The question is whether those other players can put those shots into the hoop. Reynolds Carter & Graves haven't exactly been scoring machines.
Making the E8 means you won one game against a quality team. Diamond was outstanding in that 2 point win over 13th seeded UT Martin. DeShields scored 15 points on a sparkling 3-12 from the floor. She had nice games against Mich St and SC but again came up short vs. Stanford, going 5-15. Her 3 point shooting for the tournament was a less than impressive 3-15.
I'm willing to say that very few players "lead" their teams in the NCAA's as freshmen. DeShields may well do it while at Tenn. But it seems to me that her legend has been written before she's accomplished anything to deserve it.
