I agree it's unacceptable. If the current regime isn't working, then the Cs should hire a free-throw shooting coach, a reputed specialist like Palubinskas for example, and "ask" Rondo to work with him. Even Shaq shot his free-throws at nearly 70% when he was properly coached.
When exactly did Shaq ever shoot 70% from the line in a season? Did I miss something?
He once shot 62% in one year. One!! Other than that he's a 53% FT shooter his whole life. I don't call one year at 62% good coaching. I call it a statistical aberration. I call it a career year. One that was a whole 2.7 percentage points higher than his second highest year.
If that was good coaching his increase in shooting percentage would have stuck. Over the next 5 years it was never above 50%.
Rondo got shooting coaching and instruction from Mark Price, a great shooter. He has Ray Allen on his team and a great coaching staff at his disposal. Give him time. It's only December. He shot 38% from the line in November and 61% from the line in December. I think improvement is coming. Mark Price even said in an interview that we would notice the difference in his shooting towards the end of the year, not the beginning. Rondo has never done anything for me not to trust him, his talent or his work ethic. I expect improvement and am willing to be patient with him.
