Langs has already seen the issues and has moved to quickly fix them. Namely the "option" routes. After watching TA for 2 years, he and the receivers have shown the inability to be on the same page. Langs, IIRC, is stopping this. Definitive routes that the receivers will run and TA will know. IIRC, he is also limiting the route trees or progressions that TA has to go through. Great. TA looks right and then throws right.
If Langs can simply have TA do the following, we will see improvement. Maybe not in completions, but TO's...
a) Look left and then throw right
b) Look the safety off
c) Implement more PA to get the safety or CB to bite and get single coverage at a minimum
d) The rarely used pump fake to again get the DB's to bite
e) Lean heavily on the hot read or RB out of the back field ala Marlon Lucky
There is so much game film on TA, DB's lick their chops to get to play a QB whose eyes you can really read. Langs changes that, TA improves. All of these did not involve new techniques, plays or terminology. Its simply having TA scan the field or look off a DB with his eyes....
With a dedicated staff that knows how to fix things (see KB's comments on Williams) we will be better technique wise than we have been in years.
You know....something just dawned on me.
If TA knows the WR has multiple routes he can run and he knows he has had trouble reading the defense the same as the WR so they are on the same page, I can understand him having a hard time not staring down a WR while he is running the route. I can see in his mind thinking..."Hey, I need to see what he is going to run". Now, if the WRs have set routes and he knows if he calls a certain play, the WRs are going to be in certain spots, it can be easier for him to look right and know the WR is going to be in a certain spot when he looks back left.
I have said all along that I believe these set WR routes are going to be a big factor in improvement, I'm starting to get even more excited to see how it all works out.
