    Part V -- Two Year Team Trends

    We've looked at preseason matchups using a number of different prior season stats, and found some useful tips. Perhaps though there is some benefit to looking at a slighly longer window of a team's prior regular season performances?

    First off we will revisit the notion of the "G-A-P" grading system, which for reference we classified as:

    • Good -- teams with a 10 or more wins in the prior regular season
    • Average -- teams with 7 to 9 wins
    • Poor -- teams with less than 7 wins
    Now, rather than look at one team's status against another, we will simply focus on the two year trend for a given side:

    The key thing to take away from this database query is that teams coming off a poor recent season (6-10 or worse) have been excellent spread bets on the road in the preseason, and this is especially true for teams coming off back-to-back poor years. Indeed the 'poor-poor' sides are 69% as away dogs over the past six preseason schedules.

    Other than that the numbers aren't that striking, and perhaps even surprising in that teams with back-to-back good years have been above 50% against the line in preseason, even though they would be assumed to have the least to play for and are more commonly favored.

    The other two-year trends we wanted to investigate dealt with a revisit to the offensive/defensive ranks concept of the Preseason prior year Offense/Defense article. In that, we graded teams on points scored and points allowed as again either good, average or poor. The areas of note there were the extremes -- teams with a top 10 offense and defense, and teams with a bottom 10 offense and defense.

    Rather than produce the whole table, we'll give you the best of the findings:

    • Teams which have been ranked 21st or worse for two straight years in points scored are a dismal 13-33 as home favorites in the preseason (but conversely a respectable 11-8 as home underdogs)
    • Teams which two years prior were among the worst teams in points allowed, but improved to be either average or good in the most recent season have been reliable "go-againsts" as home favorites, posting a 12-34 record.
    • Teams with bad points scored in the prior season were solid road dogs regardless of their two-year previous offensive capability (69-40 record).
    • Similarly, teams with bad points allowed in the last year are excellent road dogs, especially strong if their two-year back points allowed was either average or good.
    If all this is starting to sound like a broken record, it's because there is an inherent bias in the six year sample -- away underdogs did well, and consequently home favorites did not. Still, there is some reason to believe that getting points in an essentially meaningless game is a good thing!
