are you good at keeping records? most casual players have NO IDEA how good or bad they really are.
people spend tons of time on research, but really don't know if that research is paying off.
before i became a subscriber to fantasy cruncher, i noticed using the "lineup rewind tool" on my free trial period that the "value plays" that they had performed much better than rotowire, numberfire, and my own value picks.
originally my own value picks were usually 6 thru 9 hitters in the batting order from big run scoring teams (priced below $3.5k salary.)
once i started tracking what cruncher value plays were doing, my value plays improved alot, so i became a subscriber after the trial period.
hockey became my best game after making a big effort to increase aspects of the game each month a year ago. (like taking a month to get better at picking goalies.) no offense to the cruncher prediction maker but from 2/27 thru 5/7 of this season, their top goalie play averaged 4.38 points per game (which is good, so i'm not knocking it at all.) after specifically trying to improve JUST GOALIES earlier in the season, my #1 goalie averaged 5.30 points per game for the same time frame - and the cost per goalie start was even a little lower with mine. that doesn't sound like a big deal, but it's a 21 percent improvement at goalie. if you improved "value plays" by 10 percent or "wingers priced $7,500 or higher" by 10 percent, you'd start cashing a lot more. you'd be having lots more fun, and probably sleeping better at night after looking at your results.
for your basketball stuff, let's say you love 4 players and 3 of them under perform, do you have any idea why? were those 3 playing back to back nights or 3 games in 4 days? were all 3 of them playing on the road or were their teams supposed to lose based on the vegas line?
sometimes it's not rocket science. home teams usually score more than road teams (god bless the home team official scorer who gives a rebound to a guy not even under the basket) and teams favored to win by vegas usually score more than the other team. tired teams under perform more often than not.
pick something specific and try like hell to get better at that instead of trying to get better at 6 things at once.
if you make your question more specific, these guys can help.
i'll throw this out there and see if it helps. on youtube... type in decision tree analysis in the search box and find the one by victor lavrenko
(this helps some people and a giant light bulb goes off, some it doesn't and that's fine too, it's all about if pattern recognition works in some peoples brains)
a lot of the decision making for lineups in daily fantasy is kind of like coin flips. if heads is good for you, find out how to be the best "heads landing" flipper you can be.
