The Tom Brady era is officially over for the New England Patriots as the quarterback announced Tuesday that he was going to do the previously unthinkable and continue his NFL career with another team. In a period where the world of sports has screeched to an absolute standstill, all eyes will be focused on where the six-time Super Bowl champ ends up. Meanwhile, on the other side of the country, the chapter of Philip Rivers's career with the Los Angeles Chargers officially came to a close, as the eight-time Pro Bowler agreed to a one-year deal with the Indianapolis Colts

As players who will be 43 and 38 years old at the start of the 2020 season--whenever that might be--the two quarterbacks aren't likely to turn their new respective franchises into the top-tier squads on their own. Still, each guy has enough left in the tank to provide a level of competence at quarterback that only some teams are privileged enough to even have--though that might apply to Brady a bit more than it does to Rivers.

Of course, they're also not the first aging NFL star to make a late-career pivot to another franchise, and they certainly won't be the last. Brady and Rivers will have these other famous players to compete against with regards to how well they succeeded with their new franchise.
