Who is "Duante" and what does that guy have to do with the Dolphins?
If you're going to talk about the Dolphins QB, it would be helpful if you learned to spell his name - "Daunte"
That said, Culpepper was a very good downfield thrower with the Vikings and I don't think Martz' system would hurt him. And, as with all QB's, you make downfield throws only when you can adequately protect a QB - that mean's extra protection or keep teams off-balance with successful running, good play action fakes, and good short passing attacks. Also, Culpepper's knees should be much better - He has another 7-8 months to continue to rehab and that should help.
But, Martz is not going to be a prime candidate anyway - so this discussion is likely mute.
