It is quite possible neither Fowler or Matthews are Rams in 2020. But it's still a fair approach. Personally I'd have taken Winovich at 70 (or 61, or 56...) but I get it. You can't draft future starters and depth at every position in one draft. They significantly helped the future of their secondary, added a playmaker on offense and depth on the DL and OL.
Who knows but the 2020 Draft could, in theory, be much more heavy on offensive talent (QB, WR, etc.) that pushes edge talent to them- IF they need it.
