You are off base on context, content and conclusions.
The context was you saying giving up a 2nd rounder for Thomas was like using a 2nd rounder in the draft on a player who may be less likely to become as good. My response was to say that you aren't talking apples to apples because there is a pay element with Thomas that doesn't apply to a rookie draft pick.
As for content, I said it would make it more difficult to sign others. and the undeniable reality is there is a limit to how many big contracts any team can give out. The more spent on one player, the less is available for others. That's not even a question. A salary cap sets a budget, and that's how budgets work.
As for conclusions, you really had to make a laughable stretch to decide the fact that the team pursued Watkins but wouldn't pay whatever it takes to get him means they were unwilling to pay a big contract. It does not because regardless of whatever the Cowboys cut off point was, it would have been a big contract, had they signed him, and they were willing. They just weren't willing to go quite as high KC. The fact that you think it is a negative that they weren't willing to go to a ridiculously stupid level to sign him is even more laughable. Being willing to pay a big contract does not dictate a team has to be willing to pay a ridiculous contract.
And I did not concede that Thomas was too expensive across the board, because the expense isn't just in salary or just in the draft pick, and I clearly said the Cowboys felt like both the contract and a 2nd round draft pick is too expensive. I agree with that as well.
