Fezzik and rest of the board....need help

Fezzik and rest of the board....need help I'm already using 2 different sets of power ratings, however I would like to add one more.. Can you guys give me suggestions on who do you think has some respectable ones or the best of the best out there? Thanks in advance as I highly appreciate the feedback!
I would be interested in hearing some good sources for power ratings as well. I make my own and then blend in other opinions from some free sites for the perfect recipe of poop through the first 4 weeks. I like Football outsiders DVOA rankings and Andy Iskoe's ratings on vegasinsider ([url]https://www.vegasinsider.com/nfl/stats/iskoe-spreadsheet/[/url]). What are the power ratings sets you use?
