When players with relatively low salaries significantly contribute to their team, there's a likelihood that they'll receive a nice bonus in the form of performance based pay increases for that season, "determined by playing time relative to a player's compensation."
According to figures being released (we reference Tom Pelissero at 1500 ESPN), Cincinnati Bengals linebacker Vontaze Burfict led the NFL with $299,465 in performance based pay for the 2012 season. His base salary during his rookie season was only $390,000; standard for a first-year rookie.
Burfict led the Bengals with 174 tackles, including double-digit numbers in 11 of his 14 starts, culminating with a staggering 23 stops against the Baltimore Ravens during the regular season finale. Cincinnati signed Burfict as an undrafted free agent following the 2012 NFL draft. The second-year player broke a Bengals record for most starts (14) by an undrafted free agent during his rookie season.
Typically most players receive something, but those numbers will be released soon enough (no, we don't have them yet).
