Well, as a stat guy by trade and degree, IMO stats really break down in football as there are too many variables (players, calls, formations, opponent reactions, down/distance scenario, penalty, etc, etc) to pinpoint a given success or failure with great accuracy. Many of the stats are too subjective. Also, team make-up seems to change very frequently. Footbal is not baseball where larger sample size and 1-1 matchups are more easily obtained.
That said, there has been some very good detailed work on trends and correlation strength. Overall, the numbers do show that being an efficient pasing team and defending the pass correlates to higher Winning %. However, it doesn't really say how all of those situations are born or comprised of different teams/schemes/talent/score/etc.
For example, everyone can find stats that say Romo is a better passer than Kaepernick or Wilson (I make this assumption form bias and reading some comparative stats here and other places). For example:
- Romo has the highest 4th Qtr Rating in NFL history at 101.1 (as of beginning of 2014). Sunday it was 107.7 in the 4th qtr on 14 passes. Last year it was 105.6. The inferrence can be made that he knocked the rust off as the game went on and all may be well.
- Romo had a 79.4 rating in the 3rd qtr on 4-9 passing
- Romo threw for 281 yards total
- Kaepernick had a 4th qtr rating of 100 in the 4th qtr throwing 2 passes.
- He had a 47.9 rating in the 3rd qtr - throwing 8 passes completing 3
- He threw for 201 yards total
- Russell Wilson had a 142.7 4th qtr rating with 4-4
- I can also say that 13/14 QBs posting an overall QBrating >95 won (Robert griffen was 12th at 96.7)
- I can infer that teams not defending the pass well have a higher propencity to lose (so that is holding)
- 8 players were >100 yds rushing and were 6-8 Murray and West being on the losing teams
All of that is interesting, but each game unfold differently.
Could it be rust from Romo? sure. But the eyeball test raised more concerns than quelling them. These INTs werent heaving hail mary/punt to end the half (Balt 2008), they weren't Witten kick INTs, they were more uncertainty and lobs.
My concern with Romo all along was that he modeled himself after Farve - but never had that arm strength. Once the escapability goes, he cannot rely on the arm alone to make those throws. You dont need a canon - hello Manning. But Manning throws the ball quickly and throws receivers open with those floaters. Holding it a split second and waiting for
seperation is not a luxury Romo can afford as he ages.
Also, it should be noted that the defense greatly benefitted from SF letting off the gas. They went into ball control mode and tried to hold the clock to keep their defense fresh. They lost 2 starting secondary players and were short Bowman, Smith, etc. Kaepernick threw
10 passes in the second half and 2 in the 4th qtr. One huge pass was called back on a off PI. Not impressed with the defense - outside of McClain
In summation, stats are interesting and fun, but not universally telling in Football.
