I think that neither will get there in their first season. I'm expecting some awkward games at first from both players. Kampman struggling with dropping back and having to go those extra yards to get to the QB. Cutler with the lack of a decent WR (Although he does have some good TEs and and good HB).
Eventually, I think they'll both get there, though. I think that Kampman will get something around 16 sacjks in his second year, if he gets over 8 sacks in his first (Otherwise, he's not playing for us anymore, I think).
Cutler will get there eventually, as well. I think it'll a little longer, because I think they want to develop their young WRs. (Devin Hester and their 3 draft picks this year)
It's all just guessing, though.
