ALAMEDA, Calif. -- Through two preseason games in which hes played slightly more than two quarters, Raiders quarterback Derek Carrs numbers are downright bad.Carr is clearly not happy about it. To a certain extent, however, he also expected it.Entering his third NFL season and the second in offensive coordinator Bill Musgraves system, Carr is using the preseason to experiment with throws and plays that likely wont be used in the regular season.That might sound contrary to the normal theory of honing in on what works best in the preseason and tightening it up for when the games count.The Raiders, though, want Carr to embrace the opportunity to test the boundaries of his skills.Sometimes people are going to be mad at me for certain things in the preseason but (quarterbacks coach Todd Downing) always tells me its a great opportunity to see what you can get away with, Carr said Tuesday. I take that really to heart and do it.In seven drives with Carr at quarterback, the Raiders have scored two field goals, punted four times and had one end on an interception.While Carr has completed a modest 60 percent of his passes (12 of 20), he is averaging just 4.1 yards per pass attempt and has a quarterback rating of 48.3 that is by far the lowest among Oaklands three quarterbacks.On more than one occasion, Carr has forced throws into tight coverage. On others, he has put the ball up for grabs downfield while throwing off his back foot.Carrs longest completion in the two preseason games was a 22-yarder to wide receiver Michael Crabtree against the Arizona Cardinals.You know what it looks like when it looks good, Raiders coach Jack Del Rio said. We work on fundamentals a lot. We want to be able to block people, shed blocks, tackle, throw it and catch it ... some of the basic things that its really all about.Teams rarely reveal their regular-season strategies during the preseason. That figures to be the case more so this week when the Raiders host the Titans on Saturday night.Oakland and Tennessee also play each other in the regular season on Sept. 25.Both sides Im sure will hold a few things back, Del Rio said. Youre not going to show everything you want to do in the regular season in a preseason game.That means more experimenting from Carr.Its not a decision thats going to hurt us, Carr said Its a decision, if it works, its going to be a great thing for us. If we can continue to build on that, can it help us? Thats really all it is.I try not to do it too much but obviously I will do it during the preseason. Its a great opportunity and its a great time to do those things because when you hit Week 1 youre not going to try something new. Youre just going to do what youre supposed to do.Game notes Wide receiver Amari Cooper attended practice but did not participate. ...

Cheap Jerseys . -- Derrick Rose shook off poor shooting early to hit clutch shots late and Carlos Boozer had 20 points and 13 rebounds to lead the Chicago Bulls to a 104-95 preseason victory over the Oklahoma City Thunder on Wednesday night.Before the Stanley Cup Final began, Chicago Blackhawks head coach Joel Quenneville decided to split up the dynamic duo of Jonathan Toews and Patrick Kane against the Boston Bruins. Neither player had a point in Chicagos 4-3 triple overtime victory in Game 1. Kane assisted on the Blackhawks lone goal in the Game 2 loss. And Game 3 was a shutout loss. So Toews and Kane have combined for one assist in three games of the championship series, in which the Blackhawks are facing a 2-1 deficit. Is it time to get back to basics? Should the Blackhawks reunite Toews and Kane? If so, who should play on the left side? In the regular season, Kane led the team in scoring with 55 points, followed closely by Toews at 48. Both players shared the team lead in goals with 23. Currently, Toews is centering a line with Marian Hossa, who missed Game 3 due to injury, and rookie Brandon Saad. Kane is playing on a line with Patrick Sharp and Michal Handzus. Neither line appears to be showing much offensive spark, especially in the last two games with the Blackhawks scoring just one goal on Tuukka Rask. Another power outage in Game 4 could result in Quennevilles crew heading home facing elimination on Saturday night. So it seems like an easy decision to put your two best plaayers on the ice at the same time to maximize your offensive output.dddddddddddd But doing so would give the Bruins the opportunity to utilize the imposing Zdeno Chara against the undisputed top line in every situation. If Chara and defensive partner Dennis Seidenberg are successful in neutralizing Toews and Kane, the Blackhawks would be left with a weaker second line that would be required to take on a bigger role. Should Toews and Kane be put back together, who should join them on the left side? Saad has only five points in the playoffs so far, including a goal in Game 1. Sharp is tied for the team lead in playoff scoring with 15 points, including the lone goal in Game 2. Bryan Bickell was the Hawks most consistent player coming into the Final but his ice time has gone down considerably in each game - it was less than 12 minutes in Game 3. Having said that, he would bring a size element that Toews and Kane may require to somewhat offset Charas physicality. Should the Blackhawks stay the course and keep Toews and Kane apart in hopes that one of their lines will start producing? Or should Quenneville put all his eggs in one basket and take his chances against Chara? And who should be the third egg on the line? As always, its Your! Call. ' ' '
