Pro Football Focus has a
free agent tracker which includes each player's 2018 PFF grade and number of snaps played.
Pro Football Logic also has player ratings.
I decided to throw together a formula using each of those numbers to estimate how much each FA should be worth. I made 2 estimates for each player, one based on his 2018 PFF grade and one based on his Pro Football Logic rating. On the whole these estimates line up reasonably well with the FA contracts that we've seen.
Here are the 25 most overpaid players among this year's free agents in amount per year, where I credited each player with whichever estimate was more optimistic (so these are the guys that both PFF and PFLogic were down on):

I have included franchise tagged players here. The lists leave out RFAs and guys who were traded and then signed a new contract, and maybe some others.
Obviously NFL teams know some things that aren't incorporated into PFF or PFLogic ratings, and my method for turning those ratings into salary estimates is imperfect, and the thing I'm doing here will tend to underrate guys like Bell who missed time in 2018. But these at least seem reasonably plausible as lists of good & bad signings.
