First off, it's possible for a father to provide a solid analysis of his son's strengths and weaknesses, even when fatherly bias is taken into account. In addition, to use Donovan's connection to Rick Pitino as a reason for him to be disingenuous in his description of Richard Pitino as a coach seems like a cop out from a frustrated fan. Richard is young and relatively inexperienced as a head coach. That doesn't preclude him from being well prepared. He has, and will continue, to make mistakes as he learns on the job.
I didn't see anything that Rick Pitino or Billy Donovan said that I didn't already believe after watching the first two seasons under Richard Pitino. The coach seems to understand the game and has a vision for what he wants from his team. Currently, he is trying to implement a system on the court with (primarily) inherited players who aren't really well suited to that system. He seems to be recruiting new players who will better fit that system (Mason, McBrayer, Konate, etc.), and time will tell if he'll be successful in judging and developing talent and winning games.
In the first two years this team has won some games against superior teams (Michigan State this year is an example), and they've also looked lost on the court at times. I won't give Richard Pitino 100% of the credit or blame for either of these things, as the players are ultimately responsible for how well they execute what the coach is asking of them.
At this point, I'm willing to give Richard Pitino the next 2-3 years to recruit and develop players that fit the type of game and system he wants to play, and determine from there whether he can be successful through how competitive the team is, and overall wins & losses.
Sorry, just a little shameless pat on the back for myself where I pretend how all knowing I am.
