I'm dubious about crowning kickers. I'm pretty sure there are some "We found a kicker" posts about Zane Gonzalez from 2019 when he finished the 8th best kicker in the league.
Prater has a long and proven career. Ryland may just be benefitting from the psychological boost of not being the guy so can play pressure free. Or he may have found his groove. Hard to say.
He was the worst full time kicker in league last year by some distance. Joey Slye made 79.2% of kicks in 2nd to last place, Ryland made 64%.
I'd be wary about moving on from a proven vet just yet. Keep him on the PS, if anyone tries to claim him they can move him up. Or chances are if he goes elsewhere it would only be temporary and we can bring him back later.
