# Get the Lead and Keep It

You’ve heard numerous times in broadcasts of college or pro sports a variation of the following statement made during a recent MLB televised game between the SF Giants and St. Louis Cardinals, “The Cardinals are 65-0 this year when leading after 8 innings.”

Most often when I hear these declarations, I roll my eyes at its blatant obviousness because every MLB team has a very high winning percentage when ahead after 8 innings. It’s just more striking with the Cardinals because the number is absurd.

The same kind of stats are uttered all the time in basketball, “When team A is ahead with 2 minutes to go, they win 87% of the time,” or “When team B shoots 55% from the floor for the game, they win 89% of the time.” The truth of the matter is that fair and even poor teams win at very high percentages when ahead with 2 minutes to go or when they shoot 55% from the floor.

You can also take most stats-rebound differential, turnover differential, OER, DER, etc. and concoct the same types of seemingly spectacular stats. The “sizzle” of these statements is really not commensurate with the facts. In truth, these types of utterances are merely another example of statistical sliding scales.

For example, if I take the premise to its most absurd level, I might say, “The Spurs win 100% of their games when they are ahead by 5 with :01 left on the clock.” Logic tells us that only a fluke ending will result in a loss for not only the Spurs but also for every other team at any level with any record. Now, change the statement to include “ahead by 2 with :30 left on the clock”, and there is room for failure. The level of success with these terms certainly isn’t 100%-even for the best teams. You get the picture; the combination of more time on the clock and a smaller lead creates more opportunities for the team that is behind.
