The Texans are screwed in regards to this negotiation. Tunsil will wind up leaving the Texans for better money and the Texans will be standing there with their pickles in their hands trying to figure out how they will put a positive spin on what just happened.
I don't understand how this statement fits the statement you quoted. Evidently the Texans already offered to make him the highest paid OT. You say he has the Texans over the barrel because of the leverage he has. Then you say he'll go to another team for more money.
Does he have another team leveraged as badly as we are? Why would that other team pay him more than the Texans are obviously willing to pay?
