It is an inane scree based on an assumption without any evidence.
The assumption that the author makes is that Kelly consciously holds back players in their 1st year to save their 5th. Yet he doesn't produce the name of any player that would fit into that category.
Kelly has shown a willingness to play guys in their 1st year if they demonstrate the ability to be effective in their roles. Any notion that guys like Mayer, Tyree or Lewis wouldn't have played this year had it not been for the "free year" is wacko.
