The Miami Dolphins are expected to meet with New Orleans Saints offensive tackle Terron Armstead on Monday after the other big-name free agent in that position opted to join the Cincinnati Bengals instead.
The Dolphins - 45/1 to win Super Bowl LVII - were interested in ex-Dallas Cowboys star La'el Collins, but his decision to go to the 22/1 Bengals seems to have had a domino effect.
Armstead was generally viewed as the best tackle on the market earlier this month and when he remained unsigned through the first days of free agency, many thought teams were baulking at his asking price.
The 31-year-old's history of having missed at least six games in five of his nine seasons through injury is also a concern, but when he has played, he's been one of the five best left tackles in football.
The Bengals moved for Collins when the Cowboys released him on Thursday in a cost-saving move, parting ways with the 28-year-old after seven years.
Collins, whose biggest struggle has also been staying on the field, joins a Bengals team desperate to upgrade an offensive line that couldn't consistently protect quarterback Joe Burrow, who was sacked 70 times last season - including the play-offs.
Cincinnati have also added free-agent guards Alex Cappa and Ted Karras from the Tampa Bay Buccaneers and New England Patriots, respectively.
Miami also need veteran help on their young offensive line and Armstead, who has been to three Pro Bowls since being selected by the Saints in the 2013 draft, would give the Dolphins a big upgrade.
