The Buffalo Bills recently signed wide receiver Duke Williams. It’s not the first time in recent memory that the club has brought in a player prior to free agency actually opening.

The Bills took a swing at cornerback Vontae Davis last offseason before free agency opened, tabbing him as their replacement for EJ Gaines across from Tre’Davious White. Buffalo got one tackle out of Davis.

As the story goes, after an inconsistent preseason and start to the 2019 season, Davis decided enough was enough. He retired. But he didn’t even wait till his second game with the Bills was over.

Down 28-6 going into halftime, the Bills returned to the field to face the Chargers without Davis. The 30-year-old retired and went home. Literally.

For that, the Bills’ signing of Davis earned him the No. 2 spot on ESPN’s list of the five-worst free agent signings for last season.

Here’s what ESPN’s Dan Graziano wrote about Davis and the Bills:

2. Vontae Davis, CB, Buffalo Bills

Deal: One year, $5 million This wasn’t an unreasonable deal, price-wise, with only $3 million guaranteed. No, the reason this deal is on this list is the pesky little fact that Davis RETIRED AT HALFTIME of the Bills’ Week 2 loss to the Chargers. Buffalo certainly can get some of its money back, but I think it’s more than fair to say the Bills didn’t get as much out of Davis as they were hoping to get when they signed him.

Davis certainly merits a spot on the list and while it isn’t a good look for the Bills to appear on such a list, it’s hard for any club or forecast that a player might walk out in the middle of game. Prior to leaving the organization, Davis often posted on social media and embraced “Bills Mafia.” He didn’t respect them enough to stay for another 30 minutes, though.

The only free agent signing to land ahead of Davis the Cardinals’ decision to sign quarterback Sam Bradford. He inked a $20 million, $15 million guaranteed contract before only playing in three games before being benched this season.

It was likely a close race, but the financial incentives for Bradford likely gave him the win, of sorts.
