Top five QBs who could be replaced in 2015

4. Ryan Tannehill, Dolphins – The Dolphins starting QB has played reasonably well in his two years as a starter, but the team still has not been able to get above 8 wins. The Dolphins pinned their hopes on Tannehill when they drafted him 8th overall in 2012 and need him to elevate them in the playoff competition in the AFC. If Tannehill continues to struggle when the game is on the line (8 career losses decided by less than a touchdown), the Dolphins and new GM Dennis Hickey may be inclined to simply cut their losses and start with a new QB.
