Numbers dont lie, he's going to help big time. I also think Henne's arm is stronger than Ortons so those numbers for receptions over 15 yrds are only going to get better.
That wouldn't be a stretch if he keeps himself on the field. Warfield was great, but not prolific. Duper-Clayton were great in their day, but I'm not so sure they were top 2-4 in the league in their time. Another benefit of Marshall is that this basically eliminates the need to draft a pass-catching TE. An overall TE yes, but a David Martin TE won't be necessary.
