On Broadway and in your community center production of Hamilton, a “triple threat” is somebody who can sing, dance, and act. Oh, you thought I was threatening you because it’s Halloween? No, no, no! I have something much scarier than a bedsheet ghost costume to present to you: it’s a player who can run, pass, and catch! On Sunday, our favorite comeback kid Christian McCaffrey scored touchdowns by rushing, receiving, and passing. Of course in an offense with Jimmy Garoppolo, it would take a brand new running back to actually throw a passing TD, amirite? With the days of Kordell Stewart and Antwan Randle-El long gone, could we have the next — dare I say Joe Webb? — could we have the next great gadget player in Christian McCaffrey?
