Also, don't forget, these "ringers" play for another team they are perfectly happy with. They will return to that team for the following season. Thus, it isn't building the team. It is clearly an attempt to stack the roster to win those last few games/tournaments at the expense of the players who have put in the work since day 1.
There was no implication of this in the OP. We can't forget something we don't know. My opinion on this topic is based on the facts that I've been given. Certainly, if there are extenuating circumstances, my stance would be reevaluated. But, given the information I have received, and the knowledge I have of the game across many levels, I stand by everything that has been posted. I am also, still, in agreement with Swampboy.
