The Patriots have reached an agreement on a four-year deal with seventh-round draft pick Alfonzo Dennard, per Shalise Manza-Young of the Boston Globe. (The defensive back confirmed his four-year contract on his Twitter account shortly after the report.) Dennard, who was taken 224th overall by New England, was originally believed to be an early- to mid-round pick, but a number of incidents (including the alleged assault of a police officer -- he still faces a May 30 arraignment for the incident) likely caused his stock to drop in the weeks leading up to the draft. The 5-foot-10, 205-pound cornerback was a first-team All-Big Ten corner as a senior at Nebraska, and came away with 97 tackles (69 solo) and 21 pass breakups over the course of his college career.
