Grissom, who was the 97th overall pick, played both sides of the ball during his time at Oklahoma. He finished his career at linebacker, playing the position for the first time as a senior.
As a member of the Patriots, Grissom will likely play outside linebacker in the 3-4 of the New England defense.
Grissom is the third player from Oklahoma selected in this year’s NFL Draft. Initially projected to be a third-day draftee, Grissom must have impressed the Patriots to earn such a high draft grade. ESPN's Mel Kiper said after Grissom was drafted that he projected the former Sooners linebacker to be a sixth or seventh round draft pick
Grissom was a All-Big 12 honorable mention this past season, during which he started seven games, made 39 tackles and had 3.5 sacks.
After starting for the majority of his final two seasons, Grissom finished his career with 88 tackles, 17 tackles for loss, eight sacks, two interceptions, two forced fumbles and three fumble recoveries, including one that turned into a touchdown against Alabama in the 2014 Sugar Bowl.
