The Dolphins built around quarterback Tua Tagovailoa and his two speedy wide receivers, but something still seems to be missing.

Tua Tagovailoa suffered another concussion in a career that has been full of them in Week 2. Here's a timeline on the Dolphins QB's head injuries:

Miami Dolphins quarterback Tua Tagovailoa isn’t giving up his playoff hopes — at least not yet. The Dolphins had just seen their three-game winning streak end with a 30-17 loss to the Green Bay Packers on Thanksgiving evening when Tagovailoa addressed the fact that Miami is two games behind Denver for the final AFC wild-card spot at 5-7.

Despite another efficient performance from Saint Louis alumnus and Ewa Beach native Tua Tagovailoa, the Miami Dolphins had their three-game winning streak snapped at the Green Bay Packers on primetime on Thanksgiving.

A dichotomy of mentality and physicality is driving the Miami Dolphins, who don't want Tua Tagovailoa to step into unnecessary hits, but are praising his lengthiest stride: a verbal cue pulled from his interest in boats.

Tua Tagovailoa and Mike McDaniel hold out hope the Miami Dolphins still can make playoffs even at 5-7, trailing Denver for final spot by two games.
