I am concerned that squatting this much weight may hurt his knees, but I admit I am clueless about this type of thing.
You are not as clueless as the "coach". Catchers’ knees (joints) take a beating as it is. Your son needs to keep his knees and legs flexible but putting excessive stress (275 lbs) on the knees is not the way to do it. Catchers need to avoid stress on the knees if possible. Many use the "kneesavers" product while catching to REDUCE the stress on the knees. I think a low impact resistance work out on something like an elliptical machine is the most effective and safe way for a catcher to build stamina in his legs.
As far as weights go --- baseball players and weights will always be a an area for controversy. After doing research I limited my son (catcher) to 50lbs of weights. He never did "squats". He only used the weights to build the core and upper body. He did use some light weights on the "leg extension" attachment of his weight bench. In high school preseason he would do deep knee bends to "condition" his legs prior to the start of the season --- but no weights. In college he used the elliptical machine --- no weights.
