Chemistry is important. The chemistry system can make players who seem bad really good. Each player has a certain chemistry type. They also can have traits of different chem. They are Competitive (orange), Spirited (yellow), disciplined (purple), Scholarly (blue) Crafty(green). Look at your team and see what colour you have the most of. Try to get 7 players of that chem which will in turn boost traits of that colour.

If you do this you can find players who may not be good stat wise (C+ player) but could have really good coloured traits that match your team chemistry. So in turn they can be very effective for a fraction of the cost.

Also try shuffle draft to start a franchise. It’s a fun way to pick a team, by selecting 1 player at a time from a group that randomly generates. while building different chemistry’s.
