I don't mind mid pricers (obviously), but they can be hard to pick. I do prefer Heeney to Miller and Martin on current role in that sort of price range, until he gets Horsed anyway.
Lower priced mid pricers ($200K to $400K) are different for me - you don't expect keepers at this price point. Players starting in the $400K - $550K or so range, I try to avoid unless I would be happy to have them in my final team.
For me, I don't particularly want to end up with either Miller or Martin all year at this stage - definitely on my watch list for corrections though. Others may think they are potentially keepers and would happily start them. I don't have either for now, but mainly as there are so many other potential decent starting picks this year. Martin I prefer to Miller if I had to pick one, but would need to cut someone to fit him in.
I'm not great at SC, so maybe I'm the one doing things wrong. I'm trying to base picks less on my own opinion this year, as it's always got me in trouble in previous years. All 30 of my players are in the top 60 most chosen overall, but I'm sure there are plenty of players outside that range who would be equally good or better picks. I'm tempted by some, but trusting the majority opinion for now. No idea if this is the right strategy or not, but trying something a bit different to my usual methods.
