Franchise Help:

[Daseal]

1) When a player gets ridiculously good and I try to trade them with just a bit left on their contract (either a year or franchise tag) it won't let me. If I try to trade with more than that the cap hit is ridiculous. Anyone know how I can trade players?
2) At some point I normally get stuck so deep in a cap rut I have to restart my season because I can't sign enough players to fill my roster. How do I create more cap space, and is the only way to save that money cutting my big name players?
3) Ive tried a lot of fantasy drafts to see what works well, what do you guys suggest? There's not a huge difference between backs like LT and Portis, not big enough to blow a first on it. The defensive line is kinda a bust to spend a lot on. I normally get great CBs/Safeties. With a really good DT and sometimes a good LB. WRs seem great, QBs are important, and line evolves as the years go on. Any hints to drafting/building madden friendly team?
