Tannehill does this every offseason with wr's so it's nothing new. Greg Jennings and Jordan Cameron participated when they were newly signed, but didn't help much. Stills does it too as do a lot of the new younger guys that come along. I'm pretty sure Landry was participating in the past also.
I had completely forgotten that Greg Jennings was a Dolphin for a season. Let's hope the Amendola signing is a little more fruitful.
