This goes beyond one tweet. It's been pretty constant ripping of Fleck from day one.
It's not about strength of recruiting, decisions on game day, or even what PJ says post game to the press when analyzing the game. Majority is directed directly at PJ. What PJ says, how he talk, what PJ's vision for the program is. Reusse pretty much criticize anything PJ, without saying what specifically he doesn't like about the direction PJ is going.
What, you don't want PJ trying to recruit good players?
You don't want him visiting hospitals?
You don't want him holding players somewhat accountable?
Reusse never says, be he takes pot shots constantly with very little actual substance and has treated him disrespectfully by not even addressing Fleck by his preferred name / initials, always referring the PJ as Phil instead of PJ. Much of it's subtle, but it's a bully mentality. Most bullies don't physically beat the hell out of kids, but it's taunts, spitballs, verbal assaults which eventually build up.
It's the ultimate troll job / bully mantra by Reusse at Fleck.
Since Fleck has been here, it's been obvious that Fleck has been enemy number one of Reusse. That's not hard to see. What has PJ done relating to football which would cause this much negative attention? A 5-7 record in your first year? His recruiting class? Anything tangible has not been horrible, so Reusse has gone only negative on any area he can.
