The problem as I see it is that it will probably cost a bit more than a few second rounders to get rid of Lee and Noahs contracts. I really can't see who would be willing to take then on unless they get paid really well.
The second thing is that I think kp wouldn't be happy on the team and why should they will have to overpay him massively on two years time to keep him maybe even a max contract and that might not even be enough.
I really think they are in a bad position and they might have to sell kp to get some value to build on. If they do Boston could be a great place for a hard working guy like him!
