Versatile Frontcourt Defender with Production Gaps to Clean Up
Costner profiles as a **rebounding-and-rim-protection forward**: at Seton Hall Prep in 2006-07, he posted 5.9 rebounds and 1.2 blocks per game while also contributing 2.0 assists, showing a useful all-around frontcourt skill set. He was a committed St. Peter’s recruit and was ranked among New Jersey’s better shot-blocking performers, which points to defensive value and activity level. The downside is modest scoring output, so he looks more like a role player than a featured offensive option—best for a team needing energy, size, and help-side defense rather than a pure scorer.[1][2]
