Jennings saw limited action this past season and struggled to get on the same page with quarterback Ryan Tannehill when he was on the field. The 32-year-old made only 19 receptions on 36 targets with 208 yards receiving and one touchdown.
In an offseason interview with ESPN's First Take, Jennings said Tannehill didn't stack up with the top-tier signal-callers he'd played with during his heyday with the Green Bay Packers.
"I guess what I'm saying is he's far [from elite]," said Jennings of Tannehill, via ESPN.com's James Walker. "I'm being honest. None of us know...It's like he's been handcuffed. I've played with Brett [Favre], I've played with Aaron [Rodgers]. I've played with great quarterbacks. So you can sense, you can quickly tell if one has it or not."

Although Jennings did leave room to suggest Tannehill has untapped potential, his candid assessment likely didn't do him any favors for his case to stay in Miami.
Starting fresh seems to be the logical outcome for both sides. At this juncture of his career, Jennings wasn't worth the considerable financial investment the Dolphins were slated to have in him.
That isn't to say Jennings doesn't still have some good football left. It's more a function of Miami's current roster, which features young, promising receivers in Jarvis Landry, 2015 first-round pick DeVante Parker and explosive former New Orleans Saints standout Kenny Stills.
New Dolphins head coach Adam Gase is lauded as an offensive genius and has plenty of weapons in the receiving corps to work with as he tries to get the most out of Tannehill.
As for Jennings' future, he hasn't had a 1,000-yard season since 2010 but does bring a ton of experience and football knowledge to the gridiron. Any team in need at receiver would be wise to at least consider Jennings a possibility or bring him in for a look during this year's training camp.
But there's a possibility Jennings may go unclaimed until teams get through the draft and other high-priority free agents are signed. In light of those circumstances, Jennings could become a solid bargain for a prospective suitor.
