Dolphins signed a shockingly talented undrafted free agent that the rest of the NFL forgot to draft to attack glaring need

The Dolphins certainly did that by getting UCF cornerback BJ Adams, a player that could have certainly been drafted.

A to Z Sports' draft analyst Destin Adams mentioned BJ Adams as a Senior Bowl winner back in January.

"UCF's BJ Adams was one of the stars of one-on-ones from day three. And even more interesting was how hyped up he got after every rep he won. He simply had to let the WR know every time they lost. Adams showed off his overall speed and physicality. He proved that his press-man coverage skills on tape at UCF are the truth. I wouldn't be shocked at all if we saw him rise into day two of the draft for teams looking for that style of corner, especially with his 6'3" size." — Destin Adams.

Adams had a prolific final season at UCF. He finished it with an 86.4 man coverage grade according to PFF, allowing an 80.9 passer rating when targeted. Most of his snaps came as a boundary cornerback, which is particularly good news for the Dolphins, since their best corner on the roster is Kohou, primarily a slot player.

Adams fell in the draft because his athletic level is not overly exciting. He tested at a below average 4.33 Relative Athletic Score. He is a tal corner, but light. The player has decent speed and poor explosiveness. However, he still manages to be efficient to close at the catch point and to play physical against opposing wide receivers.

According to Dane Brugler from The Athletic, the cornerback was graded as a sixth/seventh-round prospect.

"A one-year starter at UCF, Adams was an outside cornerback in former defensive coordinator Addison Williams’ multiple coverage scheme (Cover 2, Cover 3 and press man). He worked his way into the starting rotation as a true freshman and played in 48 games over the past four years, although he never had more than four passes defended in any of those seasons.

Adams puts his length to good use when he redirects receivers at the line and makes them uncomfortable throughout the route. He can take away passing windows with his size, but his tape doesn’t show natural ball instincts, and he must become more disciplined in his process. Overall, Adams is long-limbed with enough athleticism to match routes from press, but he plays wild and upright in his movements, and his freelancing technique leads to spacing issues that NFL receivers will exploit. He is a developmental option for man-heavy teams." — Dane Brugler.

On the consensus big board, BJ Adams was the 280th player on the board. But he peaked at 156th, which would be equivalent to a fifth-round pick—the athletic testing made him drop, but the tape is clearly much better.

The lack of athleticism probably limits Adams' ceiling as an NFL player. However, considering Miami's need and what the player showed at UCF, the Dolphins may have found a valuable roster piece without significant investment.
