No, I have simply asked for support for this assertion:
This is not a statement that can be simply tossed out as fact. My question about players worthy that he didn't use it on is, as far as I can tell, the best way to support it. If you have another, feel free to provide it.
You continue to overlook the most important distinction: the first player who deserves it. Again, the question about Roberts is not whether Bill would slap the designation on whatever monkey gets hurt in the preseason simply to get an extra roster spot, it is whether he meets the threshold. I suspect that the people you are arguing with don't even feel that Roberts deserves it. I know I don't.
