I get your opinion, I just disagree. And there are inconsistencies in using phrases like "absolutely nothing to do with," and then saying only "most" of the issue aren't on the line. Is it absolutely nothing or is it some of the time, it can't be both.
And I just disagree in general, but that's subjective. He needs better ball security for sure, but several of the fumbles have been affected by the line. His turnovers since Illinois:
1) Illinois fumbled read option. Seems like he tried to give and the back had already given up. Hard to assign blame here, although the entire play was blown up -probably why the back assumed he wasn't getting the ball. He was the right read, but had no room anyway. Either way partially on Martinez and on the back, but I would argue the line is partially to blame as well.
2) Sack Fumble! Surprise!
3) INT #1 against OSU - heck of a play by the defender, and Wan'dale needed to stay flat to no be undercut. Partially Martinez, and since he was flushed from the pocket almost before he caught the snap I give some blame to the line.
4) INT #2 against OSU - not a good throw, but freakishly weird that it was picked anyway. Also had Farniok in his lap, so partially on the line. If he can step into that throw, it's a TD.
5) INT #3 - entirely on Martinez.
So at least 3 (and I would argue 4) of the last 5 had the line at least contributing.
