In February 1996, the
Colorado Rapids selected Grafer in the 2nd round (19th overall) of the
1996 MLS College Draft. The Rapids sent him on loan to the
Long Island Rough Riders of the
USISL for the 1996 season. In 1997, made Rapids first team, playing thirteen games, gaining only one win, in 1997 and 1998. On September 30, 1998, he broke his left wrist in practice. The Rapids waived him on October 30, 1998. He signed with the
Charleston Battery on January 28, 1999, but suffered a major neck injury during the pre-season and lost the entire year. Instead, he spent the entire year coaching with the Williamsburg Soccer Club. In 2000, he signed with the
Long Island Rough Riders, having an excellent season. That resulted in him being called up to the
MetroStars in 2000 after starter
Mike Ammann was injured and backup
Tim Howard was playing in the Olympics. In one of the odder moments in MLS history, the league held a draft consisting of only one player, Paul Grafer, after he signed late with the league. The
San Jose Earthquakes selected Grafer, then traded him back to the MetroStars for
Ramiro Corrales on February 23, 2001. He retired following the 2003 season. In 2005, he returned with the RoughRiders. He played nineteen games and was named second team All League. ==MetroStars folklore==
