The biggest problem with Martz running his ideal system is protection. If he has a solid line performance, then it won't matter whether or not he's calling 75% passes and 25% runs, because Forte will still get his touches and they'll be outside the pocket (which is, arguably where he's more effective anyway).
The big issue is that he doesn't have Orlando Pace as his LT here, he has a 7th round draft pick. If the line plays like that Rams line, then his aggressive offense, fast receivers, and big armed QB will destroy people. If the line plays like last year's line, then he has to push the run more.
