ESPN is further boosting its major sports coverage by producing a raft of extra material for golf enthusiasts at the US Open. And the outlet will be doing the same during the British Open, along with Wimbledon, the US Open and Australian Open for tennis. The network is employing a special team during the tournament (including some not normally involved in golf coverage) to supplement the main ESPN broadcasts with featured group and hole coverage, hole flyovers, shot tracking and more. Some of the extra goodies will appear on ESPN3, DIRECTV, and USOpen.com. All that means you might need to drag that extra TV out of the spare room, and possibly your Xbox, laptop or tablet. Who says watching sports reduces your attention span?
