To guys like eMac, Jenkins, feldberg they are nearing masters so age is part of the reason for falling off I suppose. One player I was expecting to develop his game much more has been david wiggins but on the vids online I've seen he try's to throw way too many power shots even when not necessary instead of golf shots. #onetrickpony
I dont know, what is up with Feldberg the first few holes of the 2nd round video from the KCWO. Some of those upshots were pretty easy and he just looked terrible, later he was throwing as far as the rest of the card. I dont think it was discs or old age. He should be able to get closer than 50' on a wide open 100' upshot regardless of age or disc.
