The top two stars out of Michigan's program Tom Brady and Charles Woodson have both done very well off the field. Netflix paid Brady $25M for an afternoon of comedians making fun of him and Woodson has done well in the alcohol business. Both get paid nicely from Fox.
Brady picked up a share of Raiders this past year and now Woodson has picked up a small percentage of the Cleveland Browns. Neither one these franchises would have been my first choice for investments but when it come to the NFL and a franchise, they only go up in value, no matter how they are run.
