It's important to remember that the Patriots treat the 6th and 7th rounds as means to obtain preferred free agents. Grugier-Hill comes from the same school as Patriots quarterback Jimmy Garoppolo and he's an athletic freak.
Grugier-Hill measures in at 6'2, 210 lbs and runs a 4.45 40 yard dash and 6.89 3 cone, and owns a 38.5 inch vertical and 10'9 broad jump.
He likely projects to be a pure special teams player, a la Nate Ebner and Brandon King, but he was actually a successful linebacker in college. He was First Team all conference for two straight seasons. He led the team in tackles as a junior, while also adding 9.5 tackles for loss and three interceptions. He added 6.5 sacks in his senior season, showing a nose for the big play.
Will Grugier-Hill even make the team? That remains to be seen. But at least he's a fun prospect to root for.
