Regardless of the shape he's in - physical shape or 'football shape' (including the mental side) - it would be counter-productive to put him on the field behind that embarrassing sieve of an offensive line. All those snazzy parts and pieces at the 'skill positions' are absolutely worthless if he doesn't have time: time to manage the huddle and game clock so he has time to figure things out when breaking the huddle and approaching line of scrimmage (something he's still working on), time to recognize blitzes pre-snap (something he's still working on), time to dissect coverages pre-snap (something he's still working on), time to identify the 'Mike' LB pre-snap (something he's still working on), time to locate the free safety, pre-snap (something he's still working on), and time to go through his progressions, identify the mismatch, and make the correct throw (something he's still working on) - including when to run, and when to throw the ball away and how not to take a sack/loss of yardage (somethings he's still working on).
Developing a QB starts and ends with giving him time in the pocket to set up and do all those things, in order. Average veteran QB's have a tough enough time doing that on their own, much less a 3rd year athelete who's still learning the QB position at the NFL level, who's only actually played all or part of 75% of the games he's been under contract for (30 out of 40 including the upcoming game he's guaranteed to miss).
This is going to sound like a knock on Griff, but it's not - Andrew Luck and Russell Wilson, he ain't.
To maximize his development into whatever he ultimately becomes, he needs time...and the biggest impediment to getting the time he needs is that crap O-line we're going to be trotting out for the rest of this Season. Sorry to be a Debbie Downer, but there's nothing but an offseason of Free Agency and a Draft that's going to fix that problem.
Also sorry to see Gruden (or whoever), making the choice to start McCoy on MNF against the Cowboys, for the following reasons: there's nothing invested in Colt McCoy - he's been in the NFL long enough that he's a known commodity, with a known ceiling, and it's a low ceiling. Colt is a game-manager with limited upside, and lacks the arm strength to work the whole field, and subsequently limits the amount of offense we can install to plays that only extend about 20 yards beyond the line of scrimmage. He's the 'safe' play. Teams with something to play for use the 'safe' play. At 2-5, with a largely 2nd string NFL caliber defense missing maybe not it's best, but it's most key player (DeAngelo Hall), and one of it's few other players who would actually start for another NFL Team (Orakpo), the 2014 Redskins are not going anywhere.
Despite Cousins' propensity for erroneous decisions, he's still an investment, and it's our investments who should be getting the on-field work. Also, with Cousins in, we're capable of opening the whole playbook, which we must be able to do in order to even try and compete with the Cowboys. Also, opening the whole playbook gets everyone else on the offense who may or may not be here next year, much needed reps with the entire offensive package. Colt McCoy does not have the arm or core strength to get the ball to DeSean Jackson 50 yards downfield. The Garcon TD on Sunday was 90% Pierre, and that play isn't going to be there very often when McCoy is starting a whole game against a team to prepare vs his limitations. You take that deep threat away, and it makes the whole game easier for the Cowboys defense to squat down inside the short middle area that Colt is capable of delivering the ball in. When they do this, they take advantage of his other liability - he can't throw the ball hard, either, and has a limited trajectory (height of throws). When pass defenses are in squat mode, they can get places within the limited area faster, and linemen can get their hands up because angles become more predictable, which leads to bat-downs, knock-downs, and interceptions.
Those of you who want to enjoy a night of 'Charlie Check-down' have at it. Seeing as how the only reason we have a shot in this game is that history says regardless of the caliber of the Teams that hit the field, you can throw the baby out with the bathwater most of the time the Redskins play the Cowboys. In that situation, regardless of the mistakes he might, or might not, make, I want the guy on the field that has the arm to make all the throws, because the throws that Cousins can make, that Colt can't (the deep bombs that stretch the field and keep the defense from squatting), are the kind of throws we need to threaten them with to keep them honest and possibly hit the big play. Not likely to win this game regardless, but limiting the offense, and taking away the threat of the big play is one sure way of limiting what little chance there is.
Frustrating.
