Just need to look at what's available in free agency, and what's not available.
- You can probably find a WR1: between Higgins, Evans, Pittman Jr or a trade, someone will be available
- You can probably find a decent TE1: Dalton Schultz is good, and they might be able to just bring back Hunter Henry, who was fine
- You CAN'T find a QB1: there's Cousins, Baker (who are not necessarily world-beaters themselves) and then that's it. Assuming they stay with their teams, you're looking at backups/bridge guys at best
- You CAN'T find a LT: Tyron Smith is a big maybe. They next best guy is Trent Brown...
Considering the above - I would spend on WR and TE in free agency and try to get a mid-level RT and a bridge QB. I would then draft a QB at 3 and investigate moving up into the late teens/early twenties for a guy I can make my left tackle.
