I'm not opposed to bringing back Davis if the room looks a certain way. In fact, if they end up trading Lazard (or cutting him), Davis fits in well as a WR3/4 with experience.
However, Davis wasn't that productive as a Jet, and then he left the team during camp last season. Can we trust him to be productive? Can we trust him to make it to Week 1?
The good news is that his contract would likely be cheap for those reasons.
