Teams receiving four of the 10 best compensatory draft choices this year have NFC West teams to thank.
The NFL awards compensatory choices based on net losses in unrestricted free agency, calculated by factors including salary and performance.
According to AdamJT13, the Seattle Seahawks' signing of Sidney Rice last offseason helped the Minnesota Vikings land a fourth-round pick -- 128th overall, the second-highest of the 32 selections awarded Monday.
Oakland received the 129th pick thanks to Seattle's deal with former Raiders tight end Zach Miller. Green Bay landed the 133rd pick for losing Daryn Colledge to Arizona, and Oakland picked up a fifth-rounder (168th overall) for losing Robert Gallery to Seattle.
UFA additions and subtractions this offseason will help determine how comp picks are awarded in 2013.
