Big Ben's value later vs LT's value now?

[butthead]

I drafted Rodgers in the first and Shonn Greene in the second. I also drafted Roethlisberger late as insurance for taking a first round QB, or preferably, to trade him later in the year when his value goes up. But, I can turn Roethisberger into LT right now.

My question is....how panicked should I be about Greene after one game? If I hold onto Roethlisberger until his value is higher, I could be in a huge hole if LT buries Greene on the bench. I was hoping for a bigger score than LT with Big Ben later, but after that first Jets game I think I might have to make the move now.

What do you guys think?
