I disagree with Strawman on regarding moats. Network effect. Teams won't want to pass on data when players are traded for fear of passing competitive advantage about the team as well - positional play etc If a team thinks they will get competitive advantage by switching providers. Teams may, in future, prevent league-wide lock in agreements if they think they can gain advantage by using other software/hardware.

I think there is a real risk of this happening. This business won't scale as well as a software company for a few reasons (in my view). 1. Hardware devices are required and this is an area that is developing extremely rapidly. Medical sensors overlap this market (blood pressure, insulin levels, etc). Ongoing development will be required to be able to measure the 'next' thing. 2. Elite teams will require close, time consuming relationships. They will constantly be interested in additions and changes to get performance advantage. 3. In contrast software companies have virtually zero cost per sale and much less customer contact to determine product upgrades.
