We’ve mentioned it before (Dime #34, “Players 2 Watch”), but after seeing how good Kobe and LeBron have been this summer, it warrants another mention: How have the Lakers and Cavs done nothing to improve their rosters when they’ve got the two best players in the League in their primes? You’ve got teams like Boston and New York making major strides to get better, and teams like Houston and Orlando — even if you don’t agree with some their moves — are at least trying to do something significant. But all L.A. has done is make one useful draft pick out of three, re-sign Chris Mihm and Luke Walton, and bring in Derek Fisher, while Cleveland is going into ’07-08 without changing a clearly flawed roster at all. It’s crazy that the Mitch Kupchaks and Danny Ferrys of the world are seemingly content to let Hall of Fame talents waste their prime on fake contenders. Yesterday there was some sign of front-office life in Cleveland, though, as it’s being reported that the Cavs are looking at Dikembe Mutombo and Allan Houston. That’s a start, even though you are talking about a couple of NBA relics. Obviously Deke would bolster Mike Brown‘s D, but it’s still not addressing the “LeBron right, LeBron left, LeBron up the middle” offense. H20 could step in and take Damon Jones‘ spot as the designated bench shooter, you know, since Allan can actually shoot … ‘Melo (who actually has a solid team around him) to the Denver Post: “My record speaks for itself. When the ball’s in my hands and the game’s on the line, I feel like there’s a 99 percent chance the shot’s going in.” … After Jamaal Magloire blew off Canadian national team coach Leo Rautins once already this summer and then said he’d only play if Canada made the Olympics, Rautins told the Toronto Sun, “The line that just killed everyone here was the one where [Magloire] said if they get there (to Beijing) he would show up. Man for man, everyone said at that time, ‘We don’t want you.’” The coach later added, “I haven’t talked to Jamaal, but I’m tired of chasing him. Would I like to have a guy of his size on the roster? Sure. But these guys worked their butts off to get there and if they don’t want him, he’s not playing. I don’t care if he begs to play.” Yeah, but if Steve Nash waits until the Olympics, shows up on gameday and says he’ll play 5 minutes per half, how much you wanna bet everyone in that locker room says “Yes” in a heartbeat? … Speaking of Nash, Jed was on the way home yesterday when he e-mailed to say he saw Nash on the bottle of Clearly Canadian … Dajuan Wagner‘s road back to the NBA is gonna have to go through Poland, where he signed with a pro team this week … By now you’ve probably heard that Francisco Elson broke his eye socket while playing for the Holland national team in a game against Belarus and will be out for about six weeks. What we wanna know is, Elson has to be dominating in a Holland/Belarus game, right? Then again, Sam Dalembert hasn’t exactly been tearing up the FIBA Americas tourney against some subpar comp … If you missed it, Twins pitcher Scott Baker had a perfect game going into the 9th last night. Then he walked the first batter of the inning. After getting the next guy out, KC’s Mike Sweeney came up with Baker still going for a no-hitter. Right when Sweeney smacked a single to left, the Twins color guy deadpanned, “I never liked him anyway.” … We’re out like Magloire …
