Colts fans might be getting antsy about the team's quiet offseason, but Pro Football Focus says they should be happy with what general manager Chris Ballard has done.
According to PFF's offseason improvement index, which predicts a team's increased percentage of wins due to the value of players' wins above replacement, the Colts are the second-most improved team in football this season — just behind the Denver Broncos, who added Russell Wilson.
Naturally, the bulk of this jump comes from replacing Carson Wentz with Matt Ryan at quarterback. Other moves the Colts have made this offseason: Trading Rock Ya-Sin for Yannick Ngakoue, signing Mo Allie-Cox, Zaire Franklin, Tyquan Lewis and Matt Pryor to extensions, and signing Armani Watts.
