What I didn't see coming was Tannehill becoming a decent NFL QB.
I fully understand the point you're making, and I think the point is wholly valid. But I have to point out that since joining the Titans, Tannehill has in actuality been way better than "decent." Let's play a round of "guess the quarterback":
Quarterback A, last 14 starts:11-3 record, 3,674 pass yards, 28/6 TD/INT, 102.3 rating
Quarterback B, last 14 starts:11-3 record, 3,602 pass yards, 31/6 TD/INT, 116.7 rating
I'll give you a hint... one of them is Ryan Tannehill, and the other is 2018 MVP Patrick Mahomes. And their head-to-head record during that time is also 1-1, which is fun.
(For what it's worth, QB A is Mahomes and QB B is Tannehill.)
Let's play another round...
Quarterback C, last 17 starts:13-4 record, 36/7 TD/INT
Quarterback D, last 17 starts:15-2 record, 36/8 TD/INT
One of these quarterbacks won the 2019 MVP award in a runaway vote. The other quarterback crushed said MVP on the road in a divisional playoff game en route to the AFC championship game.
(QB C is Ryan Tannehill, QB D is Lamar Jackson)
Now, I'm not being a homer here and demanding that everyone proclaim Tannehill as the GOAT or this season's MVP or anything like that. But what I *AM* saying is that he is way, way, WAY better than "decent." His performance has literally stood neck and neck with both Patrick Mahomes and Lamar Jackson since joining the Titans organization, and has played a full season's (and postseason's) worth of games. He is playing at an elite level, and this is no longer over a small sample size. I'm not generally a fan/follower of Colin Cowherd, but he did a great piece this past week on swallowing his pride and acknowledging that his first impressions of Tannehill and the Titans (vs Mahomes/Chiefs and Jackson/Ravens) have been totally wrong. These 3 players and teams have been incredibly comparable for about a year now.
In other Titans news, Derrick Henry is a beast who does things I've never seen any football player do before. I can't decide what's better- when he chucked Josh Norman aside horizontally this past week or his spinning Earl Thomas a full 180-degrees so that he became his own personal blocker in last year's divisional playoff. I'll go with the latter, because it was the playoffs but even moreso because of the trash talk Thomas made prior to the game about the non-issue (ha!) of handling Henry. Either way, I've never seen ANYONE manhandle would-be tacklers like this before.
I'm also very eager to see if the Titans can sustain the level of play they showed vs Buffalo into this next week and beyond. That Tuesday night COVID-impacted game had all kinds of special circumstances and "us against the world" setup... Can the Titans bring the same intensity to the rest of the schedule, especially when they're not "sneaking up" on everyone anymore? As a long-time Oilers/Titans fan, I've seen too many times where the Titans win all the games they're not supposed to, but also throw away the ones they're supposed to win handily. The real champions play excellent football consistently.
