Vince Young is starting his comeback with the Saskatchewan Roughriders in the CFL. If Young has success, it might give him a chance to get back in the NFL.
Several notable quarterbacks have played in the CFL and NFL. Warren Moon and Joe Theismann began their pro careers north of the border. Doug Flutie had an eight-year run in the CFL before returning to the NFL.
Young is 33, and he hasn't played an NFL regular-season game since 2011 with the Eagles. But if he can recapture the form that helped him earned two Pro Bowl selections during his time with the Tennessee Titans, he may generate interest from NFL teams who are hurting for a quarterback.
