Bill Belichick looks for leadership from his players in various ways. He looks for it on the practice field. He looks for it in the classroom and off the field. He also looks for it when things don’t go well. For the Patriots’ special teams unit, that would be last week. And Matthew Slater is the captain of that unit. Slater was seen yelling and getting after his team after allowing several big plays last week in the 41-28 win over the Texans. It was about the only area of the game that didn’t go as planned.
