Senior Year Stats according to MaxPreps:
Nkoski Perry 106comp/164att=64.6% for 1,778yrds 16.8ypc 24TD to 4INT 130.5QBrating .... 53rushes for 97yrds and 4TDs
Cade Weldon 169comp/276att=61.2% for 3,135yrds 18.6ypc 19TD to 11INT 106.8QBrating.... 96rushes for 368yrds and 11TDs
Perry ran a lot more as a junior (95rushes for 287yrds and 11TDs). Basically Weldon can also run, but he definitely throws more picks than Perry does.
But I think Perry has a better arm too. One thing I definitely like about Weldon is his release quickness, when he decides to throw the ball its out of his hands immediately. Perrys release is slower for sure.
