Depends on what you're looking for, I'd say. You can find a lot of NFL safeties with significantly better 3 cone and shuttle times, if you're willing to take less on size and 40 time. He's a very good athlete for sure, but a guy like Molden, for example, is just a different physical profile that I think might be more desirable in the role that we're looking for:
Molden:
Height: 6006
Weight: 198
40 Yrd Dash: 4.39
20 Yrd Dash: 2.55
10 Yrd Dash: 1.43
225 Lb. Bench Reps: 23
Vertical Jump: 37 1/2
Broad Jump: 10'09"
20 Yrd Shuttle: 4.14
3-Cone Drill: 6.85
Speaking purely in terms of athletic ability, the difference between Molden and Mays/Barrett seems to be one of size vs. quickness, and for the safety that we're going to start opposite Chung and have on the field with Spikes, I would probably take quickness.
On closer inspection, if you de-emphasize the 40 time and just look at 3 cone, shuttle, vertical and broad jump, and 10/20 yard dash, here's a closer comparable:
Barrett:
20 Yrd Dash: 2.50
10 Yrd Dash: 1.50
Vertical Jump: 31 1/2
Broad Jump: 10'01"
20 Yrd Shuttle: 4.27
3-Cone Drill: 7.07
Player B:
20 Yrd Dash: 2.57
10 Yrd Dash: 1.49
Vertical Jump: 34
Broad Jump: 9'11"
20 Yrd Shuttle: 4.24
3-Cone Drill: 7.11
Player B is Chung. At this point, though, it's really just reminding me why I think obsessing over measurables is dumb. It helps clarify the raw material that you're working with re: Barrett, but that's not going to make or break him as a player.
