I have a harder time believing he's playing Free since he's only been at safety for 2 weeks and the Free is the quarterback of the secondary. It's not outside the realm of possibility, but as it's difficult to distinguish between the two on the practice field, my guess is he's more likely a Kat at this stage.

As for Jones, he's seen time at both Kat and Free (not Nickel as Nacua usually slides over to that spot), so could fill out the two-deep at either position in my opinion.

Good thoughts.
