Well, it could be done. But man would it smart.
Assume we'd want Thomas:
1. Asking price is a first round.
2. Have to include Okung. He'd only offset 2.4 of Thomas' 4.4 remaining cap figure.
3. Recoup cap space by moving money forward. Dangerous.
Assume we want Mack:
1. He's already said he's not leaving. That genuinely seen as a compact between him and Thomas not leaving one another.
Assume we want Thomas and Mack as a package deal.
1. 1st round pick 2016.
2. Conditional 1st round 2017 (contingent on Mack extending)
2. Okung
3. Avril
4. Move money (roughly 3 million total).
5. Receive conditional 2nd (based on Mack extending).
If we wanted to infuse OL quality, this would do the trick. We'd be adding 2 very ugly contracts. But contracts that are not laden with guarantees. Oddly, this kind of deal could be attractive for both teams. Seattle needs LT and OC help. Cleveland needs picks, generally need out from under these deals, needs pass rush DE help and would like to get something for Mack who is generally assumed he won't be there (like Irvin here).
Seattle would have to rely on elevating Marsh and Clark to meaningful roles. Avril is such a great player. But we're talking about getting great players. Being an all pro for a team like Cleveland is saying something. So there has to be some significant give. And Seattle is able to absorb in some fashion, the loss of Avril.
Avril's contract is attractive for Cleveland and for us, because it's almost all base salary. So the cap relief for us is maximized. And for Cleveland, they have flexibility if he is injured.
These two contracts are basically the only two that will provide enough relief that we could even theoretically make this deal possible cap wise. Outside of the tons of moving parts issues, Seattle's cap situation makes it astronomically tough to even theorycraft.
