After 9-10 Weeks of OD then what? He is then at the starting point of a decent trainee after wasting 70% of the season. If he is able to get any value from him its a much better call than pushing him to get to a starting point.
I view any Draftees that are 19 as Free Money that I can get on the market. Losing that first year is so crucial to training and I wont bother training a 19y/o no matter how "nice" they are. In this managers case even if he had 2 other trainees I felt the best move would be to cash out and utilize that cash elsewhere.
