I think he either [1] hates Fred Glass with a passion for not firing Tom Crean earlier and hiring Brad Stevens (whether possible or not) and hates everything Fred Glass or [2] is a total troll and non-IU fan: I think it is the former. I also think he is older, time is running out, and he wants to see something special before the sand in the hourglass runs out. He obviously doesn't have much faith in Fred Glass to "make it happen." Feepee is broken record, and that one track is frustration and hate: can't be easy or enjoyable to keep that going.
