re: Give up A. Brown and get back Foster/Blue

your team looks pretty weak. i wouldn't do it for Foster/Blue
Foster is too injury prone, and Blue had 1 good game against a terrible run defense. He had 3 other opportunities this year and did nothing with them.

I'd try trading Megatron, maybe for McCoy.
If you give up Brown, you need something more reliable than Foster. If you have faith in Blue, do it i guess.
Foster is a pain in the arse though.
He'll start the game, run one series and say, nah, i can't play today, and then you're screwed. He is the king of doing this.
