49ers sign former Saints corner coming off career year

There is help on the way in the 49ers secondary. San Francisco has invested myriad resources into the defensive line so far this offseason, but they made their first outside addition to the secondary Friday afternoon.

The team signed veteran corner Isaac Yiadom to a one-year deal according to Yiadom's agent, A.J. Vaynerchuk.

Yiadom has been all around the league, having played for five teams since being drafted 99th overall in the 2018 NFL Draft. Last season was his best as a pure corner, with a career-high 14 pass deflections over 17 games, eight of which were as a starter.

For those interested in Pro Football Focus grades, Yiadom, who had never graded higher than a 56.8 in a full season, finished with a 81.1 overall grade and an 80.4 coverage grade , overwhelmingly as an outside corner. His overall grade ranked 12th among 133 qualified corners, and his coverage grade ranked 15th. He had a 74.7 run defense grade as well. His 84.4 passer rating against ranked 40th.

On the whole, it appears to be a high-upside signing for what is likely a relatively affordable price. He profiles as someone who will compete with Ambry Thomas, Darrell Luter Jr. and a possible rookie draft pick for the outside corner spot, and as someone who can contribute on special teams.
