The rookie quarterback now will get some help in the film room.
The move was expected, as NFL Media Insider Ian Rapoport reported over the weekend, after the Jets released Quinn. Signing him after the first game of the season means his contract will not be guaranteed.
Smith had a rookie-like performance in Week 1, but he did just enough to get the win (using a Jedi mind trick to coax linebacker Lavonte David into hitting him out of bounds was impressive). The Jets will let Smith learn and grow from his mistakes on the field.
Quinn's signing simply puts another veteran voice in the quarterback room to help the rookie. The only question is how long Quinn keeps his spot in that room.
