While the two players might be "almost identical" in terms of their size, arm length, weight, and even their 40, what I have observed is that Bourne plays faster than Jakobi. Meyers is a dependable slot guy. But Bourne showed he can line up in the slot or on the perimeter and have success. That's something Meyers really hasn't done reliably, imho. Also, Bourne seems to be a catalyst type player. When the Patriots got him involved early on, the team did excellent things.
Thornton is a young kid at 21. Wilkerson is 25. The same age as Meyers and just a year younger than Bourne. Nixon is a year younger than both Meyers and Wilkerson.
BTW, here are the RAS Comparison from Bourne to Meyers. I don't care about the grades. I printed it to compare their combine results.
Bourne has a better broad jump and 3 cone. Meyers had the better vertical and bench. I consider the 40s to be virtually identical.
