Interesting. While its only ~$700K difference from where he was slotted, it could signal maybe that the Ravens actually don't plan on giving him a long term deal this offseason.
While not universal, most franchise tag players aren't interested in negotiating long term deals for less than the cap value, so that means long term discussions would start at around $17M a year.
With Stanley and Marlon due for lucrative extensions as early as next offseason, it wouldn't be surprising if the Ravens just decided to keep Judon this year and let him walk next year.
