New England Patriots head coach Bill Belichick decided Tuesday his team proved enough through 10 practice sessions and called it a spring. The Patriots were supposed to hold two final organized team activities sessions Thursday and Friday, but Belichick sent them on their way early for summer vacation. The Patriots now will reconvene for training camp in late July. And when they do practice again, one roster battle stands out above the rest: cornerback. Prior to OTAs and minicamp, Stephon Gilmore, Jason McCourty, Duke Dawson, Jonathan Jones and Eric Rowe all were presumed to be roster locks. And if another player cracked the Patriots' 53-man roster, New England would be forced to carry six cornerbacks.
