It has surprised me in the last several years just how easy big guys are dropped by rather small CBs. That was what I liked about Walter Payton...HE attacked the Defender. Defenders rarely teed off on him because HE was trying to tee off on them!
I brought up a few months ago how I wish the Rams included a Bad A$$ FB in their Offense. Just like Brian Alstott of the Bucs back in the day.
I will say.....As small as he is, I have seen Kupp BATTLE with the football. The game I attended in 2019 at the Coliseum vs the Saints..He had a HELLUVA catch n run where he battled for 50-60 yards.
