I feel like this is one of my real strong points that helps me in the second-halves of seasons, I'm not a fiddler.
Unless I'm desperate in one particular statistic, I'm rarely making moves. Typically my bench is full of players who are there for a specific reason. I very rarely have any room on my rosters for "the next big thing", and I laugh at these guys who are cramming their benches with the second-half call-ups. In a non-keeper league, I'm rarely if ever going to hinge my season's success on whether or not a rookie performs, or a break-out player keeps his hot streak going.
Sure, it's frustrating looking at the FA pool and seeing a ton of talent just wasted there, especially with the crap rosters that half my league has, but as enticing as those options are, none of them are better than what I've got right now. Hell... right now, in my 12 team 1-Catcher league, there are 20+ freaking catchers owned. Wtf? Why? This is just stupidity. So yes, there's probably at least 10 guys out there on the WW who should be owned, and another 30 that could be owned, but I don't need them, and I'm certainly not going to advertise the fact that the other owners need them.
Eh... maybe it's the analyst/engineer/math-geek in me, but I look at people who give into the Urge as similar to compulsive gamblers. It's a lack of self control that's simply not necessary. It doesn't give you any more satisfaction or results. Making moves just for the sake of making moves is a recipe for failure.
