Stills visited the Bills last week and now gives them another option during the playoffs should injuries or COVID-19 issues impact their receiving corps.
In 10 games this season before getting released by the Texans, Stills was used sparingly and had just 11 receptions for 144 yards and one touchdown.
This has unquestionably been the worst season of the 2013 fifth-round draft pick's career, but now he has a chance to salvage it in Buffalo should he be given the opportunity to see the field during the playoffs.
In 117 career regular-season games, Stills has caught 310 passes for 4,843 yards and 37 touchdowns. His best season in terms of receptions and yardage came in 2014 with the Saints when he made 63 grabs for 931 yards, but he was also strong in 2016 and 2017 with the Dolphins, averaging 50 catches for over 786 yards and 7.5 touchdowns per season.
Stills joins a Bills offense that was dominant during the regular season, finishing second in both total offense and scoring offense.
The Buffalo offense may not have much room for Stills when its receivers are fully healthy, as Stefon Diggs, John Brown, Cole Beasley, rookie Gabriel Davis and Isaiah McKenzie make up the top five on the depth chart.
Beasley missed the Bills' Week 17 win over the Miami Dolphins with a knee injury suffered in Week 16, however, and is listed as week-to-week.
If Beasley is unable to play in the Wild Card Round and beyond, it could open the door for the Bills to call Stills up from the practice squad and activate him.
Chemistry could be an issue in that scenario, but Bills quarterback Josh Allen is one of the best deep-ball throwers in the league and a legitimate MVP candidate to boot.
Given how the Buffalo offense is firing on all cylinders entering the playoffs, it is conceivable that Stills could step in and hit the ground running if called upon.
