OAKLAND, Calif. (AP) -- Golden State Warriors coach Mark Jackson decided to take action when he saw that his players wrote a number on the whiteboard at the team's practice facility a few weeks ago signifying a goal of at least 50 wins this season. He erased it. With training camp set to start Saturday, Jackson said he viewed the number as a target on his team and a limitation on its potential. Instead, his message to players is to stop projecting success and ''make it happen.'' ''Anything can happen where that could be a great number or it could be a number where you're putting a ceiling on us,'' Jackson said Tuesday. ''So I say let's roll the dice, let's go out and play, let's compete, let's gain chemistry and let's build upon what we did last year. I'm not a guy who would sell to the guys, 'Let's put a number up there and let's go get it.'
