It’s certainly possible, he fits the kind of veteran coming-off-an-injury that the Pats are usually willing to take a flyer on. He certainly has injury issues, as does Danny Amendola (if the Pats are in the market for replacing Wes Welker). Edelman is probably the best choice of all three of them.
Still, I’d be fine to kick the tires on him. As long as he promises not to wear a tinted face shield.
