If you have a ML team in the thick of the WS hunt - all of your pitchers are between ages 26 and 31 - which Pitching Coach is better?

Coach 1 - 84 Pitching IQ 27 Patience 95 Discipline
Coach 2 - 78 Pitching IQ 86 Patience 99 Discipline
Coach 3 - 88 Pitching IQ 80 Patience 71 Discipline
Coach 4 - 93 Pitching IQ 29 Patience 58 Discipline

The reason I ask is because the Players Guide and other Forum posts make it sound like once developed, Pitching IQ and Patience has little or no relevance. But I could have misinterpreted that or not read between the lines.

Which coach would you choose if you had the money to sign any of those 4?

Assuming you could any of the coaches for the same salary, I would take coach 3.

First three guys are a dead heat. I might go a little heavier on the Discipline if I felt like it. Or maybe a combination of age and Loyalty if I was looking for a long term guy who would re-sign (because I hate coach hiring).

The problem with them resigning is they may do it but ask for more then I am willing to pay. Id take the best one I could get for a millish or less.

Does coaching slow a player's decline in "learned" ratings? And if so, is discipline sort of the aging veteran's equivalent of patience for young players?
