As long as it's a pile on Russell thread, let me throw in another two cents worth.
For one reason or another, Russell hasn't been seeing the field. I've been attending 2-3 games per season, most times in the upper level of the stadium where you can see coverages and receiver patterns. There were lots of times that Russell had open receivers at the 10-15 yard range but opted to throw a lower percentage pass, usually a deep ball. We all assumed that it was his desire for "hero ball", but could it be something else?
Case in point is the Denver game against the Colts, 4th and one at the Indy 5, down by 3 in overtime, a do-or-die play, when Russell opted to throw into a tight window instead of a wide-open KJ Hamler. That wasn't a choice of a first down vs. hero ball nor was it that he didn't read the defense. He just plain didn't see Hamler. Is he locking onto his primary receiver and not going through his progression? Is there something wrong with is peripheral vision?
I've been through the 'clip posting of broken Wilson plays' on this forum a few times, so wont bother to weigh this post down with them again.
But no, it's not a function of hero ball everytime. There have been literally countless times when he's not seen wide open receivers 'in pattern' that could have moved the chains, beat a blitz, or simply picked up yards. Every game. Every season. I've been accused of cherry picking plays that show a blatant failure and inability to play pretty basic QB.
Experts like Kurt Warner who've done film study and pointed out failures were labeled Russ haters.
Fact is, in Seattle, SOME of his struggles related to poor line blocking. But often, that poor blocking was a result of not making a line shift that he was responsible for calling. Kurt called out a few instances of this in his videos. The D woukd show blitz. No adjustments were called. The ball is hiked, and the play, rather than being audibled to a blitz beater, becomes a jail break. He scrambles, gets dumped, 4th down and fans complain that the blocking is the problem. See the Cards game in the LRC year that we lost in overtime. Classic example of how his inability to read defense, impatience, and not making line shifts cost us a game.
Also problematic are his deep drops to get adequate view of the field. Deep drops = fewer quick, 3 step drop type plays = holding the ball longer and often being outside the envelope of your Tackles protection = pressure and either a sack, incompletion or 'necessary' heroics.
**Also important here is that a playbook with no 3 step drops and few even 5 step drops and a league low from under center number of snaps equals a MAJOR advantage to any opposing defense. The D knows generally where hes going to be on every play if he's no longer a mobile qb. They dont have to honor the quick pass. Lb can either drop into a soft zone and read Russ and D lineman can dictate pressure from whatever side they want to firce him to throw from a spot. This is EXACTLY what we did agaisnt him in week 1 last year. Pete knew where Russ wohkd set up (deep) and knew he wasnt as good throwing from the left side of the field. we simply put him where we wanted him because he is so limited in getting thr ball out from shallower drops. **
Despite being only a shade taller than Russ, Brees had no issue playing from under center and hitting his back foot on 3 and 5 step drops and getting the ball out wherever it needed to be. There are highlights of him hitting a callow crossed from the far endzone where you can't even see Drew and then all of a sudden, the ball appears in a narrow lane in the line and huts his receiver in stride.
That was a fairly common occurrence in NO. Can Russ do that? He rarely has. And the few memorable occasions where we threw an inside slant...say, on a rub route, didn't end well.
He has a good number of challenges to overcome. And if he manages to flip a switch and fix it all, he will be one of the first qbs in league history to make such a dramatic change, if not the first to do it in one season. I can't think of one right now that showed such a liability and ever fixed it.
