"perhaps this is all about Atlanta drafting Penix with no intention of keeping him, but rather trading him to another team for a couple of premium players."
Makes sense to me with one caveat - what if you can't find a trading partner?
But . . . you can always find someone who would want Penix/other quality QB once all the starting QBs begin getting hurt next season.
It happens every year and teams get desperate.
If a team was lucky, 3/4 starting QBs might go down in the same week and set off a bidding war for your #1 pick QB
