He spent two years with Philadelphia and as soon as he was released, he was chosen first overall by the Los Angeles Riptide in the 2006 supplemental draft. Bice proved to be a valuable asset for the Riptide, earning a spot on the All-Star Team, being named NB Sportsman of the Year, and helping them to the MLL Finals in 2007, and to the Semi Final Round in 2008. Greg was picked up by the Chicago Machine after the LA Riptide were dissolved in 2009. In 2010 he was again selected as an MLL All-Star.
