I do not think it is a good indication of a coaches ability to pick 2 or 3 players here and there and point to there improved play over 2, 3 or 4 years as proof or disproof of the coaches merits. There will be many 18 year olds that will show great improvement by age of 21 even if they only played pick-up at IMPE. A good coach raises the level of all the ships, I mean players, over time. Any 4th year player under the same head coach should have a very good idea of what is expected on offense and should be able to be in the right position most of the time and play serviceable minutes of defense that make up for physical limitations because of experience and technique. This is where/why I am sorry to say Coach Groce needs to go.
