I just rejoined on a premium subscription. I needed a pitcher and saw Senga at $44. Of course he has been terrible but I said what do I know and picked him up and he was worse than terrible. I have Moniak who is sitting at #20 in my league. Hittertron had him at -17.9, about 350th, though he was to play two right handers. I read the methodology and it seems great reliance is placed on rest of season estimates which probably rely heavily on past seasons and on everything reverting to the expected norm over time. Which in my limited use of the tool makes me think it does not consider breakout seasons and is not very useful this early in the season. (Although it is handy in finding if opposing pitcher is LHP or RHP). How am I wrong?
