Agree to some extent. However, if they're working off Whis's game plan and playbook and it calls for 60%+ passing then that's what you do until it gets learned. Changing your plan because of one player (like John Fox did with Tebow) isn't a solution for long-term success. If the rest of our team has learned the playbook(s) and one guy hasn't (QB), then you either teach it until it gets learned or you find another QB.
I compare our game-plan (which really only worked when Kurt Warner ran it) to those of coaches like Lombardi, Landry, Walsh, Coryell, Shula, and even Mike Shanahan etc. Not in execution or similarity mind you, but in the fact that they stuck with their game-plans (and in some cases changed the game of football) even when it wasn't working because the players couldn't adjust. Sometimes it took
years. But in the end it paid off. I much prefer long-term game-planning philosophy (which Whisenhunt seems to adopt) over a coach who plugs in plans or pieces as he goes and just hopes for the best. At times it looks downright bad, but when it works that team starts to look unstoppable.
That being said, our game-plan is wholly dependent on having more-than-capable receivers and I think we've done a really good job of drafting them. Also think a lot of our receiver acquisitions started long before Whisenhunt got here, but it definitely fits what we're trying to do. This is a pass-happy league and becoming more so. With the new rule changes (and perhaps more changes in the future) teams are going to have to pass and pass well. Not just for stretches (like SF), but all game long. We already have a game-plan for that and as soon as we can find or develop a QB who "gets it" we'll look unstoppable too.
And this doesn't even take into account the possibility of an 18 game season. When that happens the RB position becomes even less valuable. Now we have a 2-back system in this league, but I can see that going to more 3-back if the season drags on for 18 games.
The need for quality receivers will only increase. We have one of the best, if not the best, in the league, and have had decent depth at that position for years. Roberts and Doucet wouldn't have looked as bad last year under a competent QB. Fitz made Kolb and Skelton look almost average (as opposed to as bad as they were), because he can catch anything, but it's ridiculous to expect the 2's and 3's to make those catches regularly. Half the time when they got hit in the chest with the ball they were surprised.
