Sport data feeds – anything other/better than Opta? Potential for disruption?

I'm working on an app plus web site for football (soccer) fans and I'd like to create a number of widgets with fixtures, tables and results.

Opta http://www.optasports.com/ appear to me the market leader provider (and something of a monopoly). They also charge monopolistic prices.

I feel that sports has huge potential, but seems like it's dominated by Opta and ... no one else.

Are there any other FOSS or lower-cost sport data providers out there? If not, why not? Is the field open to disruption?
