You can send a player age 22-26 to winterball, only if they did not go the season before.
You can give them a single concentration. (contact, gap, power, eye, avk, defense at 1 position, speed ratings for hitters... stuff, control, movement, stamina, gb% and extra pitch for pitchers)
we will go to random.org and get a number between -5 and +5. The number will be given to that player's concentration in Website Ratings (not editor ratings), only overalls.
For 'extra pitch' for the pitchers, if they get a positive number, then they add a pitch, if negative, they lose a certain amount on all their current pitches, and they can only ask for an extra pitch if they have 4 or less pitches already.
