So why draft him then, and waste the pick?
The Rams had Three 7th round draft picks which are generally throw away picks.
It’s not like they have a lot invested in him.
They probably drafted him because getting the SEC co-defensive player of the year near the end of the draft was a good value pick even though his chances of making the team are slim like all 7th round picks.
Simply put, he was the Best Player Available at the end of the 7th round.
