Jacoby Brissett has experienced everything in the NFL from starting to playing behind Tom Brady, Andrew Luck and Philip Rivers. Brissett is already preparing for life after football, though he’s not done playing. The 28-year-old quarterback signed a $7.5 million, one-year deal with the Miami Dolphins last month. On Wednesday, Brissett became an investor in a venture capital fund co-founded by two-time Super Bowl champion Malcolm Jenkins. Several other NFL players, including Duron Harmon, Devin McCourty, Jason McCourty, Jordan Matthews and Rodney McLeod also have invested in Broad Street Ventures.
