Rocky will be an absolute lock if fit, but at this stage I don't think Gazza will be meaningfully under-priced. He's had one score under 100 and the other two have been quite reasonable. Still eight games to go, so one moderately low score won't have too big an impact of he plays out the season at his normal standards.
Even Pendles was looking cheap until the weekend. Might still be a little. JPK could be priced below his realistic potential too. No need to pay fair value on someone like Fyfe with so many other good options, in my view.
At this stage I think Rocky, Sloane, Libba and Selwood would be first picked in the mids for me, in decreasing order of confidence.
Other potentially under-priced names I will be keeping an eye on: B Smith, maybe Malceski and Hibberd, Leuey if he moves, Gray if M/F, TMitchell if M/F (especially if he stops tagging).
