OAKLAND The Warriors held their annual open practice and scrimmageon Saturday at Oracle Arena, and it was mostly fun and games. Coach Mark Jackson,micd up for approximately 5,000 to hear, played the animated role of master ofceremonies, there was plenty of crowd participation, and the rookies all had tosing and dance like in years past.But there was the more serious business of the scrimmage andit was during that time that two players showed a little something: BrandonRush and Jeremy Tyler.Rush, who was mostly a spot-up shooter a year ago, hit acouple of jumpers off the dribble and also found a way to knock down a shot ortwo on his own, when he elevated over Klay Thompson.That wasnt Rushs game last season, but Jackson said fanswill see more of that this year.He came with the reputation of not being able to put it onthe floor and make plays, Jackson said. And we knew right away that wasntthe case. Actually, last year we put him in position. There were times when wewere a cold-shooting team from the perimeter and wed say Somebodys got toput the ball on the floor and make a play.He was the one guy who did it and did it well. So theresno surprise with him doing that. One thing I challenged him with in theoffseason was being able to put the ball on the floor better and being able toplay in pick-and-roll situations. Hes very good at it and hes going to haveplenty of opportunity to do that quite a bit this year.Tyler has kind of been the forgotten man on the Warriors. Hedidnt play much as a rookie in 2011-12, and this season seems to be behindDavid Lee, Carl Landry, Andrew Bogut (when he gets healthy) and Festus Ezeli.But Tyler played well at times during the Blue-Whitescrimmage. He was on the White team, which was made up what appeared to be thesubstitutes.Tyler had effective stretches on the interior against a teammade up of mostly first-team players.He is developing, Jackson said of Tyler, in his secondseason. Hes a much better basketball player now than when we first got him. Ithink this summer has been big for him as far as working with our young guys,being in the summer league. Battling against Festus Ezeli every day. It makesyou better. Hes got a more professional attitude and hes improving. Hesstronger and he has a better understanding of the game.The scrimmage: The Blue team was leadingthe White after three quarters, when Jackson called off the fourth quarter.Jackson said he didnt want to overwork his players and felt like theyd had agood enough workout. The Blue team was up by approximately six points.The Blue team consisted of: Harrison Barnes, Kent Bazemore,Andrew Bogut, Carlon Brown, Stephen Curry, Festus Ezeli, Draymond Green,Charles Jenkins, David Lee and Klay Thompson.The White team consisted of: Andris Biedrins, LanceGoulbourne, Stefhon Hannah, Jarrett Jack, Rick Jackson, Richard Jefferson,Tarence Kinsey, Carl Landry, Brandon Rush and Jeremy Tyler.
