I have no evidence for it, but I sense that the door to get someone as expensive as Reddick is closed.
The Rams absolutely can get one of the top 3 Edge rushers in the draft using purely draft capital, and this will maintain a level of cost control for 4 years. It's my opinion that is what signing Williams, Curl and White means.
It's not the draft pick that matters if a deal for Reddick were proposed: it's the cap cost, most likely for at least 3 years.
But, who knows for sure the Rams mindset on this. They are always full of surprises!
