Just a day after offering 6-foot 10 center Derrik Smits from Zionsville (IN) HS, Butler offered the 6-foot 9 Ohio native.
Last season Fowler averaged 7.3 points, 7 rebounds, and 0.6 blocks per game in 26 games while leading Moeller to a record of 23-3 and a District Finals appearance.
Fowler plays with the King James Shooting Stars and another Butler target Luke Kennard, Franklin (OH) High School.
Butler has focused on size with three of its first offers in 2015. Smits and Fowler are true centers, while Malcolm Evans, from Jackson, MS, is an extremely long shooting guard/wing.
