right now you can get Dez in the late 2nd, and there is a ton of untapped potential for Dak. 
Per 4for4: "Dak Prescott finished as the No. 6 QB in fantasy last season despite ultra-conservative play-calling tendencies. Prescott not only had to overcome an offense ranked in the bottom-three in situation-neutral pace and pass-play rate, but also one ranked 26th in red zone pass-play rate and rate of pass attempts 16+ yards downfield."
It helps that Rico Gathers may be legit, and I love the Switzer pick.
