If this was the scenario presented to me, yes, I would do this in a heart beat. Problem is that this is not the scenario we are dealing with here.
The entire reason Clowney is holding out is because the Texans franchised him as a LB with is around 12-14 mill if I remember correctly. Clowney says he is a DE and as we know from DLAW, the tag for a DE is $20 mill. That is why Clowney did not sign the tag and report with Houston.
So, now we know why he is holding out. Trading a pick for him does not eliminate this problem, Clowney will expect his new team to pay him as a DE, ergo $20 million. Clowney is not going to play under the LB tag for Dallas or any other team in the league, so you have to know this before you trade for him. So you are going to trade a 2nd rounder, probably higher, and have to pay him pretty much the same as DLAW. That is the real scenario we are looking at here fellas.
We still have Zeke, Dak, and Cooper to sign. You trade for Clowney and pay him DLaw money, how we going to afford to pay our triplets? Answer is we cant, at least not all of them. So who you willing to give up for Clowney? Dak, Zeke, or Cooper?
