Three links to drop on you.-- I had a lot of fun writing the Big Read this week about San Antonio Spurs coach Gregg Popovich.-- I did not have as much fun writing about sports and security in the wake of the Boston Marathon attack, but it’s a hugely important topic and I do catch up with an old friend, former FBI special agent Jeff Lanza.-- Rob Neyer with a great idea -- he asks really cool people like Michael Schur, Bob Costas, John Thorn, Brian Kenny and, well, himself, what should be the next baseball movie now that 42 is doing big box office. He also asked me.
