Sure Max, it is possible. It is equally possible, maybe even likely that they will be busts, as one of them is leaning right now.
No sacks in college, no real pass rush moves, not very strong at the point of attack, can't hold an edge. At to this, one of them is also dealing with a season ending injury that happened at a pro day.
Sure, take a chance on a player, I have no issue with that..
Except, you don't take that big risk on a player who will not be able to pay until the following season, when you already have no depth nor real threat at said position.
That is the crux of the matter.
This defense has struggled up the middle and off of the edge for the past few years. Why?
Linebackers, outside, inside, they have missed on drafting & or developing them, a for cry to how it used to be. They never used to miss on those positions, perhaps this is just the cycle. But they let a potentially great middle backer pass by them in the draft only to take a chance on an injured, not even showing flashes of potential edge rusher.
Thus, now they are desperate and have to over pay for an aged, hurt vet.
