Detroit pro athletes Jimmy Howard and Dominic Raiola will be part of the festivities at next weekend's Quicken Loans 400 at Michigan International Speedway. Howard, the Red Wings' goalie will serve as grand marshal, ordering the drivers to start their engines. Raiola, the center and captain for the Lions, will be the honorary starter, waving the green flag. It's the first of two NASCAR race weekends this summer at MIS.
