I think it might be helpful for new owners to get some tips from more seasoned players before they start making decisions on their ball clubs. I know it would have helped me in my first league, and it might prevent the new owners from getting their faced ripped off in trades (see any trade made by hartjh to sublimefargo in season 2). So, I am going to start adding tips on the blog, and if you feel like adding anything or correcting what I write, feel free.
Do not overestimate the value of velocity. It does not seem to matter in a pitcher's performance. In fact, two of the best pitchers in the league (Carlos Maranon and Edwin Patterson) have velocity ratings lower than 43.
Do not pay attention to overall ratings too much. These ratings tend to be overinflated by stamina and durability ratings. I tend to look at a pitcher's splits rating(vsL and vsR), control rating, and pitch quality rating the most when evaluating pitchers.
A pitcher with stamina over 70 can be used as a starter (over 60 if he is really good)
You can switch a player's position at anytime in the edit rosters page. I try to meet the minimums at every position, and especially up the middle of the field (ss, 2b, and cf).
A high overall rating does not necessarily make a player better than one with a lower rating. Example - A catcher with a 70 overall rating could be an exceptional hitter and very good behind the plate. But a pitcher with a 75 overall rating could have bad control, low splits, and make it up with high stamina and durability. The pitcher in this example would be useless at the major league level, but the catcher would be very valuable. Just keep this in mind.
This is a start for new owners. If anyone wants to add, please do so.
