As opposed to what someone here surmised this isn't about my teams being above the cap, they're fine or on the way there. I've dealt to get down before and it's not a big deal now. This isn't about my own self-interest.
What this is about is I am very against these posts that suggest that other teams shouldn't trade freely with the sucessful teams. Anything that hurts the overall trading liquidity is bad for PB and for all of us. Tim suggests you shouldn't trade with teams dealing with the cap unless it puts you in the playoffs. This isn't his first post in this vein(see his 12/17 post).

I think you should trade with any team anytime you can improve your own team. Don't worry about making another team too strong (unless they're your direct competition) if it gets your team where you want to go. Don't decide that you won't trade with some teams, or demand more from them, beforehand. Keep an open mind about trading with everyone.
