the problem with opening up the playbook, IMHO, is getting everyone on the same page at the same time. Every season we have added a new WR, or a new O-lineman, or swapped an O-linemans position, or brought in a new scheme with the zone blocking. What I am saying is that this offense has not consistantly fielded 75% of the same players from year to year in their same positions until this upcoming one. Add to that the fact that Carr had to learn the playbook himself before he can start running it effectively. It is actually somewhat promising to think that we might actually have an offense that has played together for most of last season, going into the next season.
I am looking forward to opening up the playbook next season. I think we will dramatically add to the number of plays that our offense has mastered. It is all about WR/QB timing and Defensive reads with Palmer's offense. Carr and our WR's should be significantly improved in both the next season, I hope. Our O-line will have a year of practice at zone blocking TOGETHER, and I see them all getting on the same page next season.
Next season should be an actual indicator of how much our team has progressed with actual NFL starter calibre players having played together for most of a season. In today's NFL you will probably never see a full return of all 22 starters on any team. But returning as many starters as we will be doing next year should definitely improve our ability to play as a cohesive unit, IMHO.
