Making him an all-around player is a good ideal. Training a 6'1" player in shotblocking is just a really bad idea. Some skills just won't matter than much for certain players.
In fact, many/most owners view shotblocking as overrated and don't train it at all, even for their bigs. I've been training bigs for 3 full seasons now and have trained shotblocking exactly zero times. I'd rather give a big man passing or jump shot training.
