The Dolphins are open to upgrading at corner if the perfect fit emerges and NFLdraftscout.com’s Rob Rang expects three defensive backs to be available in the July 11 supplemental.

But all three have blemishes and it’s a stretch to say any would be better this season than what the Dolphins already have.

Mississippi State safety Brandon Bryant, Western Michigan cornerback Sam Beal and Virginia Tech cornerback Adonis Alexander are those players.

Here's how the process works: Teams interested in selecting a player email the league with the player they would draft and in what round. If they use a fourth-rounder, then that team would forfeit a fourth rounder in next year’s draft.

Here’s what Rang had to say about the two cornerbacks:

“Beal (6-0, 185) earned second-team All-MAC honors last season, leading the Broncos with 10 passes broken up. He was overshadowed, at times, by former teammate Darius Phillips (a fifth-round pick by Cincinnati this spring) but Beal offers an intriguing upside due to his combination of size, speed and physicality. Though his numbers dropped significantly (from 55 in 2016 to just 22 last season), Beal's willingness to tackle was the primary reason why the former prep receiver was asked to make the transition to the defensive side of the ball early his career in Kalamazoo. Beal was set to enter his senior season as NFLDraftScout.com's No. 30 cornerback.

"If teams are comfortable with the off-field issues that plagued Alexander at Virginia Tech, he could wind up being the player that generates the most interest.

"[Recently], Virginia Tech officially announced that Alexander, a senior, was no longer part of the team because he failed to live up to his academic obligations. He missed three previous games with the Hokies due to suspensions, including one for testing positive for marijuana. While teams will want to investigate Alexander's character, his talent and production speak for themselves.”
