Yea, I mean, as a trainer of a former NT-21/NT player, obviously I wanted him to be the best player, but I wanted him to be the best player for my team's needs. If he happened to be good for the NTs as well, then awesome... but that was clearly secondary.
If in the future we get something to be on the national team (a salary break or something), then this may change. But for now, most teams won't be willing to change it up.
