I have been doing a lot of research on some of these players for my fantasy team, I am not going to say which ones here.. LOL. However, I always use multiple sources and try and look at an aggregate. IMO a number of those players are positioned in part because of name, hype, draft position, *upside that has not really shown yet. There are a number of guys way down the list should be higher IMO and some guys really high should be lower.. I think guys who will have a lot of power but high Ks and low OBP are valued higher then some guys I believe will be high OBP and avg but not as many Hrs etc... Which as you well know is important in 7X7.
Just my opinion..
