Prob stuff you've already heard before but, in game modifiers are much more important then people realize, a balanced build is very important, and not forgetting fundamental skills IMO. It also helps having a very good team around you obviously as Nate does.
If my team makes it to the Pro's finally(2 conf championship losses as the #1 seed) I'll think about posting a pic of his build. But i'm still learning myself and trying to improve and there's tons of ways to build a successful player. I'm hoping he'll get a few more Ints though the last 2 games, and do even better in the playoffs when I boost him

His best game(even though he did let up the only TD he ever has in 3 season, he responded with 4 ints after) came against a team with an overall 42 ranking and green in nearly every bar that has destroyed most teams in the league worse than we have. So he has performed well against top competition as well.
Also, 18 in USA Pro is pretty impressive as well, let me know how his season ends. SE Asia AAA#2 was AA and ranked higher than ALOT of leagues at the end of last season, but obviously isn't as high as a pro league let alone USA.
