- New England Patriots coach Bill Belichick said he is giving up on touchline tablet technology, just weeks after he was seen slamming one down in frustration during his team's defeat to Buffalo. The famously taciturn Patriots boss spoke at length to explain his frustration with the tablets, which are used by coaches across the NFL to review action in real time. "As you probably noticed, I'm done with the tablets," Belichick, 64, told reporters. "They're just too undependable for me. I just can't take it anymore." The NFL signed a five-year deal with Microsoft in 2013 worth $400 million to supply the league with its Surface tablet computers. Microsoft said it respected Belichick's decision but defended the performance of the Surface.
