JPW had a record-setting year last year, and yet, the offense was still painful to watch. Some of that had to do with leadership, coaching, playcalling and overall team "attitude," but last year was just the latest example of SEC Offensive Commandment #1: "Thou shalt run the ball effectively."
Bama has an awful lot of talent and experience at the offensive skill positions, but throwing the ball - alone - doesn't win games in the SEC. Remember 1969: a record-setting year in terms of offense and passing, and - oh by the way - the team went 6-5, if memory serves, mainly because the talent on defense was subpar. Sound familiar?
The only way Bama's offense is great - not good, but GREAT - this year ... if every defensive coordinator on the schedule goes blind, and allows Bama's RBs to go to the left side of the line on every running play.
RT is the real question mark this year, offensively. IMO, it will make or break the offense, and the season, since Bama will have to count on prevailing in a number of shootouts in order to win more than 7 games in the regular season. Don't know about you, but I'll be praying that the Football Gods grant us a just a mediocre defensive unit. That's not too much to ask, is it?
Anyhow, this is a brand-new coaching staff, and there will be a year or three adjustment period on both sides of the ball. New attitude, different coaches, improved S&C, all these things will have an immediate impact, but the improvement will be incremental - at best - this year. CNS can't go out there and play the game for the players, nor is he a magician. He cannot wave his magic wand, and *POOF* transform a group of players - recruited for TOTALLY different offensive and defensive systems - into ideal players for the new regime.
Until the "right" players can be recruited and trained up (which again, will take a couple of years, probably more like 3 or 4), the coaching staff have a very challenging task ahead. They have to improvise schemes and plays (on both sides of the ball) (1) to get the most out of existing talent, so as to win games THIS season, and (2) that are not so different from the coaches' ideals that, once the players are in place, a smooth, seamless, multi-year transition is assured.
Long story short, this may be another banner year for Air Bama, but unless RT shores up (and at least one of the RBs finds his identity), the overall offense will "only" be good, and not great.
