Eli Manning's tenure with the New York Giants is coming to an end, but is his NFL career also coming to a close?

Hall-of-Fame quarterback Brett Favre still thinks that Manning has something to offer, saying that “he could be huge for another team if he so chooses” on SiriusXM NFL Radio this week.

Due to an ankle injury to rookie signal-caller Daniel Jones, Manning started for the first time since Week 2 this past Monday against the Philadelphia Eagles.

He had a terrific first half, completing 11 of his 19 throws for 179 yards and a couple of touchdowns, but during the second half, Manning slowed down considerably, going 4-for-11 with 24 yards in what ended up being a 23-17 overtime loss.

Jones replaced Manning under center in Week 3.

Manning had been the Giants' starting quarterback since midway through his rookie campaign in 2004, winning a couple of Super Bowls along the way.

Moreover, both of Manning's championships came at the expense of Tom Brady and the New England Patriots, and he also notched Super Bowl MVP honors both times in the process.

However, at 38 years old, it's obvious that Manning's physical gifts have escaped him, as he no longer possesses the cannon arm he had during his prime, nor are his reflexes as strong.

Manning can still play quarterback in the NFL and can have moments where he looks good, but it seems hard to believe that he can sustain a high level of play over a full 16-game season at this stage.

Most likely, Manning will be starting for New York yet again on Sunday when Big Blue takes on the Miami Dolphins.
