USL expansion offers quick promotion for Dayton Dutch Lions 30 Nov 2010 Mike Mossel always saw the USL Premier Development League as a springboard for Dayton Dutch Lions FC. After a successful debut in the PDL last season, the Lions were pegged for promotion to USL-2. But the recent creation of the new USL PRO league, essentially a merger of the USL’s top two divisions, has expedited a process that Mossel, the co-owner of DDL, fully expected to experience in coming seasons. “Our plan was to move up to USL-1 in three years,” says Mossel. “This speeds up the process.”
