Well, let's see, teams ahead of the Cowboys possibly looking for QBs...
1. Bengals for sure (almost certainly Burrow).
2. Maybe Redskins, but they might want to give Haskins another year...or they might Cardinals it in favor of getting a new guy.
3. Probably not the Lions, but there was some talk of them moving Stafford this past off-season, you never know.
4. Dolphins are certainly a strong possibility, especially since Josh Rosen seemingly appeared DoA every since he was drafted, and apparently the current plan is for Fitzmagic to keep starting.
5. Chargers absolutely need a QB, strong possibility of them taking one.
6. Panthers just signed Teddy Bridgewater for a year (or was it two?), probably won't draft one high but you never know.
7. Browns, whatshisface had a pretty big sophmore slump, but I'd expect them to give him at least one more year.
8. Sam Darnold on the Jets also probably gets one more year.
Bengals (#1), Dolphins (#5), and Chargers (#6) seem like the most likely QB-takers in front of you, with small chances from a number of other teams. Hard to leapfrog them without selling the farm, too. Yeah, doesn't look great. There's also a a possibility of another team like the Patriots leapfrogging you, especially with their three third round picks. No, I think you're stuck with Dak, especially knowing Jerry Jones who loves "his guys" and has no interest in drafting his replacement already.
As for the Packers, it's back to drafting projects we hope turn out in the 30s/upper 20s for us...
