Do not spend coins on packs. There are cheaper ways to obtain players. Instead, save coins to spend on special offers in the Store or for bides at the Auction House.
Head-to-Head games
Decline challenges by players that are obviously pushing a stronger team. There will be no loss in fans by doing so, and the rewards for winning against a much stronger team is not worth the risk. Try to face opponents that are more evenly matched with your own team. Use the "Strategy" option to defend against specific plays that are being run against you. Because you are not in control of the defense in Head-to-Head games, take note of the plays that opponents like to run and make sure you have the most common ones in your active slots. When on a fourth down, go for the field goal if you are in range. Although unrealistic, scoring at every opportunity is the most important aspect in this mode.

Lineup
Do not rely on the "Best Lineup" option to always be accurate, especially with positions that require speed. Consider manually setting players in the WR, HB, KR and PR positions by looking at their Speed rating if all other attributes are somewhat the same.
Plays
Do not follow the CPU's play suggestions, as its choices are very limited. After unlocking a decent amount of the playbook, call your own plays to ensure that you are using the best option for the current situation.
Set rewards
When you have a potentially unwanted player, check every Set to see if one has a spot for him. Completing a Set will result in useful rewards. If the player still cannot be used, use the Quick Sell option or auction them.
