Since the Jets basically now have a full complement of receivers, this is probably just the Jets doing their due diligence, as it will soon be futures season. Anyone not under contract with an NFL club at the end of the regular season can be signed on a futures deal at that point.
Enderle, a 6-4 25-year old from Idaho, has never thrown an NFL pass in a regular season game but was on the Bears' active roster briefly in his rookie year (2011). He was with the Chargers in preseason but did not play. Enderle's only preseason action saw him go 13-for-23 for 177 yards and an interception in two 2011 appearances with the Bears.
Coale, a 6-0, 187 pound receiver, was a four year starter at Virginia Tech and got selected in the 5th round of last year's draft. He ended up on the Cowboys practice squad, but tore his ACL last year and although he was back with the Cowboys in preseason, he failed to make their roster. He also spent a week on the Colts practice squad in September. Coale was a fan favorite and caught three passes for 22 yards in six preseason games with the Cowboys, including this spectacular grab.
