You can certainly try to trade for Foster, personally I'm not a fan and I think his week 1 performance was a fluke. I like Turner, and healthy (I know, unpredictable) there's few better. If you can add Smith to the trade and get value, sweet. I don't think the Giants or anyone on that team is gonna have a stellar year.
I'll have to attack this tomorrow after work, it's past my bedtime. Why are you holding onto Collie? Just curious. I snaked myself Clayton (STL) in the FA pool and he pulled in 2 TDs today. St Louis may suck, but at least he's targeted more than Collie who is what, Manning's 4th choice after Garcon, Wayne, and Clark?
