Your sacrificing quality for quantity. 8 players in the $400k - $500k price band. 9, possibly 10 premiums. Maybe another 2 will bust out to keeper status. That leaves you with 12 Premiums and 10 upgrades to complete. You've already spent 20 trades before rd 1 starts.
Sounds good in theory to start with 14 keepers but with the lack of rookies, especially up forward, I don't see how you can avoid not having those in the 400-500 bracket
