This was a good read and much of it I agree with.
Fantasy baseball is sort of like business, in a way. You can do the best market research, attract the right customers, have the right timing, and develop the best product to cater to your audience's needs... and still wind up on the wrong end of the ledger. There's only so much you can control in prep and in transactions, but in the end, if they don't produce to expectation, well that's just the way it goes. Just when you think you have a potential steal like Ricky Nolasco, who is bound to rebound, and as (bad) luck would have it, he's still not quite performing. That said, I will say that preparation and activity comprise of 70% to the formula of success.
In the case of H2H leagues, it's more important to focus on the things you can control. By control, I mean, to focus on the categories that aren't likely to fluctuate weekly. Draft a blend of hitters, who ideally hit for power and get on base quite a bit, while paying less attention on SB and BA. On the pitching side, draft a deep pitching staff of pitchers who post great K rates and don't damage your ERA/WHIP too often. Sounds simple and while this is just one way to win the game, this kind of strategy does tend to give you a bit more say in the results.
Regarding the bigger picture of enjoying fantasy baseball... I will say that the least thing I enjoy with fantasy baseball (I'll even go as far as to say hate) is it's easy to get too wrapped up in information overload. There are so many factors to a hitter's/pitcher's success to consider, many projections to sift through, and various bits of advice to sort out that it can become really overwhelming. Keeping track of players in general alone is cumbersome and too time-consuming, if you let it become that. I'd say this is the primary reason as to why over the last couple of years, my interest in fantasy baseball has waned and why I've lessened my commitment to the game. It's a hobby, but that's exactly the place I'd like to leave it as. I enjoy the drafting season the most, in fact, because the preparation itself is more fun than the dragging through the season. By the time May comes along, I'm less excited about the game and am on cruise control, enjoying life... if not, working hard on the things I love most. It's all about having some perspective and a healthy life balance.
