That's what an almost flawless draft does for you when you get a bunch of contributors as rookies:
Jerrell Freeman (PS I think)
Six players who are having major roles in their first season. As a comparison we only got Coples, Stephen Hill and Demario of whom basically none was a starter in his first year.
And not too mention, Indy was lucky to have the record they had this year. Lots of close wins against a weak schedule.
