Obviously it depends on the college program but I believe in the majority of cases college coaches are much better "developing" players than the pros. Just a quick story....I'm good friends with the father of a middle reliever who has been pitching in the "bigs" for 5 years. His father says development in most organizations is left to the player. He says the reason is that minor league coaches fear being fired if they try to make a change. BTW, this big league pitcher went to college first. His father says that nearly all of his development should be credited to the college program. Another aside...this player was a first round draft out of college so you'd think they would be very interested in his continued development. His father says they had one goal in the pros....we hope he doesn't get hurt. Any mechanical adjustments (to this day) are made by the player and his dad (the major league team will not suggest anything).
