Bleed has it figured out.
So many people take what a coach is saying at face value and gospel. A lot of times it's just words. Many others, it means something else.
In this particular case, I believe Pitino is just worried about focus. His team has taken some mental turds on the court. He believes he can reduce distractions and hopefully improve player focus in certain ways, including getting players off Twitter.
I'd also recommend (a) stop worrying about free throws - it's a non-issue and (b) play your best players (e.g., EE's low minutes represent a coaching error if the goal is to win basketball games).
I have no idea how you can watch basketball games for any length of time and conclude that free throws don't matter. How many you shoot is totally a factor of attacking the rim. How many the other team shoots is a factoring of you fouling people...how you play defense...keeping them out of the lane etc And how many you make has a major impact on your total points in a game. How many you make in the last four minutes is often the only strategy factor in whether you win or lose. For instance the difference between being up 4 or up 2 because you missed the front end of a one and one is a major factor in the outcome. Same is true down 2 or down 4 and on and on. How can free throws not matter? It is a MAJOR box score indicator of how you played the game and who won.
You either don't watch the games and just read statistics or EE is a relative because you can't be watching him play. He did play very well versus Penn St (for EE) but that might have been the first time this year. And you obviously dismiss the free throws the other team shoots on his fouls or getting closer to the bonus (curious, is that unimportant to? getting to the bonus?) and you dismiss EE factor in making free throws too?
