 Since there are few European players who have had the chance to compete at a level comparable to U.S. college football and the NFL, many, if not most, of the European players ended up as kickers.Among the notable national players were Scott McCready, an English wide receiver who played some preseason games for the New England Patriots, the Claymores' wide receiver Scott Couper, who played a pre-season game for the Chicago Bears, Constantin Ritzmann, a German defensive end who had played for the University of Tennessee, and Rob Hart, an English rugby player who became a placekicker; he kicked barefoot.Like previous football leagues, the UFL has instituted several mostly minor rules changes that will differ from the NFL's rules.
