Eli Manning
The likelihood that Manning returns to backup Jones — something he has adamantly ruled out — is slim to none, but with precious few options, the Giants may try to convince Eli to remain at a substantially lower cost.
Manning was a positive influence on Jones and helped his development greatly, but doing that for a second season would be a tough sell. However, it would keep Manning in the league and provide him a potential opportunity to play, which he may not receive elsewhere.
Early indications are that Manning is leaning toward retirement, but if the waters dry up and the Giants find themselves in a precarious position, co-owner John Mara may simply ask Eli for a favor.
Again, the odds of Manning return to backup Jones are nearly non-existent, but stranger things have happened.
