The POINT at which they complain might differ (for instance on a promise of 10 minutes/game, Player A might pitch a fit once his average hits 8.5 mpg, Player B might not have the same reaction until his average hits 7.5 mpg), but I think any player you've promised something to will complain at SOME POINT if that promise is not upheld. I would imagine ***but do not know for certain*** that the degree to which they get upset if the promise isn't fulfilled to their satisfaction differs at season's end as well.
