good questions. Here is what I would do: get a FA (cheap) RB to platoon with Singletary. Allows us to run at the end of the games. I'd love another TE to pair with Knox, but we may have that. In the 2nd, hope that Cleveland (OT) falls to us. Having a OT on a rookie contact is a solid investment.
I'd be okay taking another TE in the 3rd, but would rather go BPA then. I don't think we need to reach for anything, and in the 3rd, there could be a good WR to take to replace Brown/Beasley in 2 yrs or so.
