The 2018 NFL free agency market was active well before free agency officially began at the start of the league year Wednesday. That means the majority of this year’s top free agents have been signed.

But a handful of solid free agents remain available on the market, ready to be signed to a new team.

If the Bills don’t think Mayfield is worthy of being their franchise QB and the Cardinals move out of the way from No. 15 to go up and get Allen, then it’s down to the Ravens and Chargers at teams that potentially could sneak away with Lamar Jackson as a QB to groom for the future. But because Baltimore and Los Angeles are in AFC contention mode, Buffalo probably can feel secure about Jackson being a strong fallback plan.

With Darnold to the Browns and Rosen to the Jets looking more like QB-team fits, pick Nos. 2, 4 and 5 create serious danger for the Bills to get stuck without a real QB choice at No. 12. While Mayfield is the wild card, Allen’s strong arm makes him the first ace out of the hole.

Allen would be the greater attraction for the Bills to target with such a high pick. Their getting equally aggressive for Mayfield would be surprising.

Restricted free agent Chris Boswell signed his second-round tender Thursday, Mark Kaboly of The Athletic reports. The Steelers still hope to sign Boswell to a long-term deal.

In the meantime, Boswell is due to make $2.914 million this season.

Boswell, 27, signed with the Texans as an undrafted free agent in 2014. Houston cut him out of the preseason but signed him to the practice squad for a week.

He spent time with the Giants in the offseason and preseason in 2015 before catching on with the Steelers in October of that season.

Corbin has gone 5-7 with a 3.33 ERA in 19 games (17 starts) overall against the Giants. He has had less success (1-4 with a 4.61 ERA) in seven starts in San Francisco.texans_030
