Soup guys? I could see them adding some depth O-Line. There are a bunch of centers/guards out there who could add depth or compete with Edwards that will be cheap. Brian Allen makes sense as a Kromer guy who was released. Evan Brown is young with potential.
At WR I would take a peek at Laviska Shenault. He isn't quite a traditional wide receiver, but a guy that you can maybe get for the minimum who can do a lot of things on the field. Durability is the biggest concern, but there have been times he has looked like Deebo Samuel or Cordarelle Patterson out there. He's still just 25 years old and I feel like he is a toy Brady could make use of. He can play inside and out, some RB, and returns kicks. 6-1, 227.
At DE Rasheem Green could make some sense. He has some sack production in the past, is a traditional DE, and is still young. James Smith-Williams is a depth end from the Commanders who has size and length and is coming from the same system. Those guys aren't really moving the needle, but could be functional cheap depth. The edge FA class is a barren wasteland outside of Mike Danna and Jadaveon Clowney.
At DT, I would like to see them maybe sign a 1 tech like Joseph-Day and then take a shot at a former highly drafted guy for the minimum like Marlon Davidson or Taven Bryan, guys who can give you some rotational interior pass rush.
