It has been the NFHS, CCA Men's, and CCA Women's mechanic for a number of years now.
We can thank Phil Bova for this mechanic. Phil was teaching this mechanic in his camps starting in the late 1980s. If one were to watch a Division I game, especially a Big 10 game from that era, one could tell who had attended Phil's camps because the T would also chop time in for Throw-ins in the Front Court administered by the L.
