I see what you're saying but let me give a counterpoint:

Do you think it's good for a team to not trade for an awesome player because they are afraid that some current players (who they like) are going to be upset about having to ride the bench?

In my view, how the team as a whole is doing (US) is ultimately what's going to be better for everyone.  Big innovations really do trickle down. And what hurts now will be to our benefit in the coming years.
