That's on Langsdorf. Quit calling long passing plays into the wind, bottom line.
The play was called by Langsdorff, the throw and decision was made by Armstrong.
TA needs to either throw to another WR who isn't double coverage, or tuck it and run.
Or, if you're a decent OC, you don't call a play that will put your QB in a position to make that throw.
Yes, Tommy should have tucked and run or checked down. But that is coaching as well (or a lack thereof)--Langsdorf should address this by being the QB coach with Tommy and drill him so he makes better decisions.
Additionally, if Langsdorf pays attention to who he has under center, he doesn't call long, downfield pass plays into the wind with a QB that has a penchant for throwing INTs and that throws off his back foot (something that helps the ball hang when you're throwing into the wind).
Short passes have been working, and we need sustained drives to move down the field. We don't need home run balls every other pass attempt.
This is why Langsdorf fails--his play selection is done in spite of the flow of the game, and not because of it. He doesn't use plays to set up other plays--he just calls the long bomb over and over and expects Tecmo Bowl results, when we don't have a Tecmo Bowl QB to facilitate his playcalling. And even if we did have the pieces in place that Langsdorf wants, there isn't much there to have confidence that he'll use them effectively.
