The Patriots certainly didn’t pick up any big name guys in rounds 4-7, but they picked up some guys who can contribute on special teams and sometimes in offensive/defensive situations.
In round four, they picked up Jonathan Wilhite. He’s a 5′ 9 1/2″ inch cornerback from Colorado. He’s very fast, instinctive, has fluid hips, can play in zone, has good footwork, is a decent tackler for a cornerback, and is versatile in that he can play the slot or the outside. Still, he is very undersized and doesn’t have ball skills, plus he has had some injuries. Still, he could eventually have a role as a nickel guy (especially if Wheatley is able to step up into a starting position).
The Patriots traded up in round 5, hoping to get Nebraska cornerback Zackary Bowman. That didn’t work out too well, as Bowman got selected one pick prior. With Bowman off the board, the Patriots went with Matt Slater. He is the jack of all trades, as he plays safety, corner, and receiver (for which he was drafted). But he was really drafted for special teams. He had three return scores last year, but is also great in return coverage.
In the sixth round, the Patriots selected inside linebacker Bo Ruud. Ruud played multiple positions at Nebraska, but projects well as a 3-4 inside linebacker with the Patriots. He was a guy that I liked a lot, I’ve had him go in some of my mock drafts. I think he could turn out to be a good rotational guy for the Patriots at linebacker. He’s got good instincts, strength, and size, so I think he might be a good late-round find.
