When I draft an 18yr older I plan to bring them up between season 4-6 depending on the need... 19 yr old is 3-5, 20 is 2-4, etc... the circumstance dictates if I bring him up early, late or right on time...
for this argument, I feel that patience is an important rating rating for stud SPs.. you don’t need to plan your who;e team 10 seasons in advance buts it’s nice to know that you could have a stud SP cheap for 10-15 seasons..
