I think Porter and Bruce are relatively equal right now. The Raiders QB situation has me a little worried with Porter but not too much and Bruce is obviously on the downside.
I would not trade Moss for Jackson and it has zero to do with being a Jets fan. Jackson is a good player but I like Moss' potential much more. Both could have some competition for balls, Jackson moreso, but I think Jackson is proven to be a 70 ypg guy for 6-8 TDs a year. The jury is out on Moss but he is really only entering his third season becuase of the injuries in year 1 which seems to be when alot of guys hit a stride. His potential is more like 80-85 ypg and 7-9 Tds, plus he may do punt returns which can always mean an extra score here and there.
