How many had him fired at week 6 or so? Going with Lewis over Henry at times...there was a bunch of huh? decisions including cutting Finch, whatever he did with kickers, spending all of training camp with "coach's pet" Pamphile as the starting RG even though he has zero games this year. How many times were we upset the RG was a turnstyle?
Since Tannehill is more like "since Tannehill" he's employed a FB, signed/used a FB (curiously the TE plays FB more...unsure of wording, add Blasingame), and FINALLY decided not to rely on Corey Davis. How many fans were upset with Davis, knew Henry loved a FB, and wanting him to get it more? There were super obvious changes and I don't really feel comfy "giving credit" for what every football fan knew.
I've watched Arthur Smith struggle, change, struggle, change, adjust, ooh that works, that doesn't....til midseason when he seemed to figure things out. He clearly needed some time and is clever and I'm all for praising him but he too would be a half year.
No doubt Mariota was bad but remember all the times people were talking about how few seconds it took for the D to get to him? A whole offseason and he couldn't come out with a line better than that? They were on pace to just edge out the worst ever for sacks.
If you're talking most growth, most in-season improvement, then I'm on board. He's still got one play on issue every game where we have to see his ego as if it's tangible, but otherwise major props to him for the second half. Coach of the year- no way (IMO).
