Leveraging data over 8 seasons of the Indian Premier League (IPL), we demonstrate the effects of competing against former teammates on a team's victory in IPL matches. If two teams, A and B, are competing in a match, and n<sub>A</sub> players from A are former teammates of players on B and n<sub>B</sub> players from B are former teammates of players on A, then if team A has smaller values of n<sub>A</sub>, it will have a competitive advantage over Team B with a higher value of n<sub>B.</sub> We call the magnitude of the difference of n<sub>A</sub> and n<sub>B</sub> the “ecosystem” factor in predicting performance. Using regression and stochastic network models, we find that the ecosystem factor significantly impacts the outcome of a match. Our findings have implications for franchise owners.

We show that the normalized probability method produces good tests of the null hypothesis of strong market efficiency but that the inverse odds method does not, with results biased against finding favorite-longshot bias.
