Deep thoughts, cheap shots & bon mots ...

Good to see Kyle Shanahan toughening up the 49ers by having them “thud up” in training camp, hit hard in pads. But I just suffered a flashback to another rookie coach, Mike Singletary, whose beloved “nutcracker” drill wiped out half the 49ers’ roster. I believe the drill was so-named because it required ballet-like moves.

The International Olympic Committee is blowing it with the Olympics. Paris gets ’em in 2020 and Los Angeles (probably) in 2024. Hey, IOC, ever heard of Las Vegas? They’ve got stadiums and arenas up the wazoo. Vegas could host the Olympics later today.

Plus, Vegas has plenty of fun stuff to do in case the Olympics get boring, which is likely. The way the world is going, by 2020 you won’t be able to get three nations together for a sports festival.

The sad question in Oakland: Where’s Alonso? The sad answer: Yonder.

Don’t want to get all political here, but if there’s any truth to the frightening new projections on global warming (you know how melodramatic those scientists are!), those East-side seats at Levi’s Stadium will be replaced by solar panels to power the AC in the VIP Tequila bunkers under the stands.

When the greens are set up super slick and steep at a major, you have turned the art of putting into a lottery.

Gregg Popovich is the NBA’s Statue of Liberty.

Roger Goodell was seen sitting in the luxury box of Patriots owner Robert Kraft at the Jaguars-Patriots practice game. Just once I’d like to see a sports commissioner sitting in the real grandstands, with the real people.

The last owner who sat out in the bleachers with the unwashed masses? Probably Bill Veeck, circa 1975. And in the bleachers Veeck installed a shower, to wash ’em.

Umpire Joe West was suspended two games after a newspaper interview in which he called Adrian Beltre the biggest whiner in baseball. West said he told Beltre he was a good hitter but, “You’re the worst umpire in the league. You stink.” There it is, proof positive that calling balls and strikes creates an emotionally charged interaction that raises doubt about the legitimacy of every call. Robo umps, please pick up the white courtesy phone.

Why did Jay Cutler leave his cushy new TV gig to return to the NFL? “My wife talked me into it, more than anybody else,” Cutler said. Now there’s a man who burns to play the game.
