How much would you bid for Latavius Murray?

Someone dropped Murray late Sunday for some reason, and I’m wondering how much FAAB anyone in my situation would bid.
I currently only have $50 (of $100) after a hefty claim put on Jefferson. Currently at 3-1 and have Mixon, Singletary, Gibson, Dobbins, Harris, Mattison at RB which is strong for my league.
