It's the ninth consecutive year the Wildcats are picked to win the league and 15th time since the 1998-99 season. The predictions announced Tuesday were made in voting by SEC and national media members.
Blackshear is a graduate transfer who helped lead Virginia Tech to back to back NCAA Tournament appearances. He averaged 11.2 points and 6.0 rebounds per game in 103 games for the Hokies.
The first-team All-SEC picks were Blackshear, Georgia freshman Anthony Edwards, Kentucky's Ashton Hagans, Mississippi's Breein Tyree and Mississippi State's Reggie Perry.
Kentucky also had a pair of second-team preseason All-SEC picks, Tyrese Maxey and EJ Montgomery.
Florida was picked to finish second, followed by LSU, Final Four participant Auburn and Tennessee.
