I tend to lean towards Cressey and his philosophies, but the above is not considered long distance swimming (by me anyway) but more as pointed out by bulldog excercises and therapy.
I guess a good idea would be to ask, during the players recruitment, the training staff on how they incorporate swimming if it is mentioned by the coaching staff the same for running.
I definetly don't want my son to work with anyone that beleives that pitchers need long distance of anything (would include swimming and running).
