Well the Niners are taking a QB at 3, and the first two are set at least if you believe all the insiders. A lot of darftniks have pointed towards Fields at 3, but the buzz seems to be someone else. I personally think it's going to be Mac Jones, but Ian is quite credible so Trey may certainly be in the mix yet.
My guess is Mac goes three. Someone trades up for either Lance or Fields, the other one falls for a while.
