This year I've learned that.... I need to find a better league to play in.
For the first time of my fantasy baseball experience I decided to commish a league. Every other year's experience has been tainted by poor league setups, questionable owners'-moves, and general apathy by two-thirds of the league. Unfortunately, taking the reins for myself only fixed about one and half of those. We finally had a decent league-setup, and I managed to keep a lid on most of the shenanigans, but we still ended up with most of the league losing interest by the ASB.
As it turned out, the roto-lead I ran away with in the first third of the season held up despite some pretty downright bone-headed moves on my part. I honestly think it says more about my opponents skill than it does about mine, when I can still win the league after trading away DiceK, Hamilton, Quentin, ManRam, and a handful of other players who I didn't get a good return-on-investment on.
Next year I'm going to take a stab at something a bit more competitive.... and not trade away so many guys who are having a good first half for slumping stars who aren't living up to their supposed "track records". A bit more patience would have served me well this year, I would have won by 20 points instead of 3.
