i follow Hockey and football (the one where players kick the ball instead of running whit it...its closer to handball.)
Go to teams: Finnish Hockey league: JYP, NHL Red wings or Duck's. and sad to see one Hockey legends #8 career end with 6-2 loss in game seven.
Football: As a kid i bought Arsenal #14 shirt, my favorite player Thierry Henry at the time. Nowadays i own and FC Barcelona Xavi's shirt and Bayer Munchen from Germany.
American handball... i usually check out super bowl, but don't follow the regular season.
Basketball. Rarely watch any games but go to team from NBA would be NY Knicks.
