I understood what you meant, and perhaps my use of the word 'sell' was not the best.
My 'NOOOOO' was in response to you entertaining the idea of this team becoming sellers. We are far from that point, IMO.
I think we should be buyers, but I don't think we should gut the farm to try to win it all this year.
Add a #3/4 starter, a solid reliever, and possibly an offensive upgrade at catcher, left field, or the bench. This would be in lieu of gutting the farm to obtain a #1/2 pitcher. This also assumes that the current players start performing like they are capable of performing.
