Going off your first mock here, I see many problems. The first one that I see, and it has nothing to do with you, has to do with drafting at this time of year at all. Rankings, including the ones you most likely used on the website you used, are too skewed towards last season, and do not take much future projections into account. Webb in the 12th, IMO, is rediculous. I agree with above about, basically your first 6 picks (sans maybe Manny), being way off. Ellsbury, Felix, Morales, Butler, Manny and Choo is not a nucleus that screams contender at all, even IF they all produced (overproduced) last season.
It just appears that this was an unspirited offseason mock where one or three teams struck gold by taking advantage of some bad draft application.
You are at the right place though, the projections and info. available at the Cafe will go a long way towards helping you out, but at this time it is WAy too early to find anything that is well tuned yet.
