Steebu and ibeatthetris pretty much nailed it. I would only add for number 2 that I have never seen a Bud Foster defense tackle as poorly as this one. Granted TO is extremely gifted at finding even the slightest crease and unlike Marshall he does not go down with sloppy arm tackles. Marshall is slippery while TO is fast and decisive. I have no idea which is better suited for our offense but glad to have both of them. TO only weighs about maybe 185 on his 6'2" frame but he runs much bigger hence the comparisons to Nesbitt which in my view is not warranted. They are entirely different animals.
For the record, I see merit in playing either QB, so I don’t want my take on your trade-off to sound biased.
I would argue decisiveness is more important in this offense. Everything happens in fractions of a second, and essentially it comes down to feel. I compare it to chipping & pitching in golf. Yes - you can gather data points on the green speeds, breaks, and other factors...but it ultimately comes down to feel in the moment. It’s a strange thing to describe because many of us come from very analytical backgrounds where we seek perfect information and rationale decision-making, but honestly it’s just too hard to consciously make decisions in fractions of a second.
That’s why blitzing can be so detrimental to this offense - it hastens the decision making. It’s my belief that regardless of front 7 alignment, the teams most successful against option attacks successfully hasten QB decision making and force OLmen to constantly consider blitzing LBs (rather than firing off the ball full steam). In the past, Bud Foster did a better job at creating disruption by generating blitz and stunt packages with DEs and OLBs (and using the MLB to track the alley, and Safeties to track the pitchman).
