Bell also wasn't a QB. The Texans have little draft capital this year. If Watson refuses to play, they're up shit's creek without a paddle. And it'll only harm their bargaining position the longer it lasts. Frankly, if I'm Watson, I tell them, "If you refuse to trade me, I'm not going to refuse to report. Rather, whenever I feel the slightest bit of discomfort, I'm going to refuse to play for medical reasons." That would put the Texans in an even worse position. Now, they'd have to fight it out with him on whether or not they'd have to pay him while he sat his butt on the bench. Regardless, if Watson is done with the team, they would have to be monumentally stupid to drag it out.
