Trick,
ENCOURAGE, ENCOURAGE, ENCOURAGE my nephew to excell in any sport he's love's playing, be it 2, 5, 1o, etc. Be the BESTEST dad you can be by allowing him to decide what sports he wants to participate in. Do not be "that" dad that forces his children to play sports and stands on the sideline berating the kids as they play. Relish in your sons play, brag just a lil to remain humble and be there for him in his wins and loses!!!
You'll do GUUUUUUUUUUUUUUUUUREAT!!!
