The coach of the best basketball team in the Southeastern Conference could finally smile late Wednesday night. “This was a fun one to win,” said Vanderbilt’s Kevin Stallings after the Commodores’ 85-76 road victory over Tennessee. “But this league is so tough. We get finished with this one and now we’ve got to play that one (at Kentucky).” Stallings is right that a 5-0 SEC record (16-3 overall) does not guarantee an NCAA bid. Kentucky started 5-0 in league play a year ago and wound up in the NIT. But the Commodores aren’t coached by Billy Gillispie, either.
