16. Eli Manning
Manning is a New York Giants’ icon. However, ironically, the Giants’ current condition is partially a symptom of his lengthy career. If he had retired a couple of seasons earlier then his team’s fans could be looking at a very different franchise in 2020. Before the Giants finally benched Manning for Daniel Jones, his gameplay plummeted dramatically as he threw interceptions.
It’s fair to say that the arrival of Ben McAdoo coincided with Manning’s decline. But age was also a factor. Unfortunately, the two combined signaled the beginning of the end of his career. His final Super Bowl win was way back in 2012, 8 years before he retired. After this, the Giants and Manning went into a slow but stark decline. He stayed with his franchise for 16 seasons, a great achievement. But it was arguably too long.
