Jaylon is a great player; reading reports, some had him going 3-4 round due to his injury. I feel Jones was too quick to grab him and maybe could have grabbed him in the 3rd at least.
Other than that, its possible the Cowboys are very confident of Jaylons progress and that maybe that info was leaked and another team was rumored to grab him first.
I don't know, but something odd had to occur for Jones to grab him in the second with some real good defensive players still on the board.
Let's all hope Jaylon:
Makes a full recovery.
Can still play like he did in college and better.
Doesn't end up with a glass knee that keeps him on and off the bench.
And that other players won't be targeting his knee.
