Dawan doesn't have the same athleticism that LaRon does, but it's pretty good. Dawan plays best in run-support, or when moving up on the ball over dropping into coverage. Landry has good size and strength and good speed for the safety spot. Dawan Landry is known as a good tackler when filling the lanes or out in isolation outside the box and good play recognition skills in the pass, but wouldn't be the type of player to drop in either one-deep or two-deep coverages.
Could the Jets make a play for the other Landry? It's hard to say, but they are down at the safety spot and unless the Jets plan to start both Bush and Allen, their roster right now needs more people at the safety spot. We'd guess that re-signing LaRon Landry would be the priority, as he'd bring more to the table under the scenario where the Jets move away from Revis this offseason.
