It absolutely does. I analyze sports professionally, and used to post picks here https://bitcointalk.org/index.php?topic=987312. Most of my analysis relied on knowing the Teams, and specifically their formations in soccer. You also have to be active in tracking their recent games because their recent performance is an indication on how they will perform in the games that are to happen a few days apart.

And I absolutely prefer Soccer over Tennis. Tennis is 1vs1, and a lot is dependent on the performance of a single player, where as in Soccer its a team effort, and the decider heavily relies on more number of people playing good. So you are likely going to get more bang for your analysis with a game like Soccer. There are also more lines available in Soccer vs other sports like tennis. The only time I bet on Tennis these days is, if I am watching the match live.
