When the Miami Dolphins took Ryan Tannehill with the eighth overall pick in 2012, the front office and the entire organization believed they had found their next franchise quarterback. The Dolphins are now four years removed from the 2012 draft, and it's still somewhat unclear what Tannehill is.

Though it's not entirely his fault, he has yet to lead the team to a winning season in four years and has a 29-35 record. If he's not to blame, who is?

Dolphins wide receiver Greg Jennings believes the coaches have to take some of the heat for babying Tannehill.

Jennings was asked if he believes Tannehill is the guy that will lead the Dolphins back to the promised land. His response was, well, not overly confident.

Via CBS Sports:

Throughout 2015, there were questions about how much power Tannehill was given in the offense with regards to calling audibles and making adjustments at the line of scrimmage. Towards the end of the season, he was reportedly allowed to do more, but that's after three-plus years of limitations.

Fortunately, the Dolphins have a new head coach now -- one who's experienced in working with quarterbacks. Adam Gase hopes to turn the team around and take them to the next level, and it all begins with improving Tannehill's game.
