Recurring issues with the team coming out flat when it has a chance to build on a big win, the team not building on in-game momentum, and Tannehill not hitting receivers in stride. There are other issues, but, to me, those three things are the most troubling.
You aren't as good as you think when you win, and you aren't as bad as you think when you lose. But not making progress on perpetual problems this team has had makes you really wonder how much better this team really can become. You can't continue making the same mistakes for three years and suddenly think they'll disappear.
