Smith is a free agent after four disastrous seasons with the Jets. The 2013 second-round pick started 29 games in his first two seasons before losing his job. Smith has completed 57.9 percent of his passes with 28 touchdowns and 36 interceptions in his career. Locker room issues and a torn ACL make Smith an unappealing option as the Giants' backup.
If the Giants are interested in continuity, bringing back Johnson is their best option. Johnson spent all of last season with the Giants. He was the third quarterback for most of the season, but he was elevated to No.
