We have seen running backs that can throw the ball before -- remember Kordell Stewart?
Vick is a medicore+ player on a mediocre+ team in a midiocre- to very bad division and conference.
I give Vick 1 to 2 years before either his clock gets cleaned and is career is over or the league adjsust to him (wait for next week for that) and he follows Kordell Stewart into oblivion.
There is a reason they don't run the Option in the pros.
Regardless, it appears you've changed your opinion here within one reply. You first stated that you had a "very low" opinion of Vick. To have a "low" opinion of someone within a relative setting involving competition is to consider him substandard in relation to his peers; to have a "very low" opinion of someone is to consider him to be among the very worst people engaged within his field of endeavor. To have a "very low" opinion of an NFL player would surely place him among the very worst players in the league.
You have now pronounced his status to be "mediocre." As such, your opinion of him has obviously been reconsidered, and it is no longer "very low"; it is "middling."
You're headed in the right direction.
