• The Texans’ Arian Foster is just trying to be the best teammate he can.
• Water doesn’t care how many NCAA basketball championships a school has won.
• A’s general manager Billy Beane will trade anyone – for a player he really wants.
• Marshawn Lynch rejoins the Seahawks before his bank account approaches Least Mode.
• Waiting for Tiger Woods to regain his winning form may take longer than a nationally televised Red Sox-Yankees game.
