Our guy with a big leg was pretty damn consistent in 2017 and 2018. I don't think Zuerlein walking has anything to do with what the Rams want in a kicker. It has more to do with Zuerlein's cost, age, and durability imo. Sometimes, kickers who seem consistent don't prove to be, and kickers who don't seem very consistent prove to be exactly that. It's not an easy position to evaluate.
Roberto Aguayo was automatic inside 40 yards in college (46/46 on FGs in college inside 40 yards and 198/198 on PATs). He sucked in the NFL. Justin Tucker was a good but not great college kicker who is going to be the greatest NFL kicker of all time by the time he retires. The Saints have a stud kicker named Will Lutz. Lutz hit only 63.2% of his FGs in his final year of college. On the Ravens, Vedvik went 12/13 on FGs in the preseason (hitting two kicks from 55+ yards and his only miss being from 53 yards) and 11/11 on PATs. After his trade to the Vikings, he struggled badly.
Kicker is such a weird position; I think it's worth taking a shot on him if the Bills are willing to move him. Sometimes, a guy just needs a change of scenery, the right coaching staff, and some confidence to figure things out. And to make it clear, I'm not saying we should put all our eggs in the Vedvik basket. He would be one of the guys competing for a spot.
