Offensive coordinator Mike Sherman promises that Tannehill will be the most improved quarterback in the league from Year 1 to Year 2. Wide receiver Brian Hartline already has noticed a "huge step" forward for Tannehill this offseason.
"He's making every throw, his deep ball looks awesome, and he's got great touch -- you don't feel like it's a rocket coming into your hands," Hartline said, via the Palm Beach Post. "His improvement has been amazing."
Tannehill struggled mightily on third downs as a rookie and went through bouts of inaccuracy later in the season. Like many inexperienced quarterbacks, he also leaned too heavily on his first read, failing to go through his progressions.
If he improves in those three areas, Tannehill has all of the traits to join the conversation of the game's most promising young quarterbacks.
