So a few thoughts, questions, rebuttals....
1. A lot of people do say, "it wouldn't work long term" or "it just wouldn't work" but why wouldn't it work? Wouldn't it make more sense to run a power run based offense in the Big 10 where it's about physicality instead of pretty boy smoke and mirrors spread offense?
2. Atleast off the top of my head, the only 3 teams I can think of that really run what I would call a Spread Offense, would be KC, BAL, and SEA. Now I'm not crazy knowledgeable about X's and O's and I'll admit that, but A LOT more NFL teams I feel like still operate under center in more of that "pro style" offense than they do with a dual threat out of the shot gun. Atleast until more guys like Pat Mahomes take over the NFL that is.
3. Isn't the whole concept of an offense to get really good at the basics over time, and then get really good at expanding on those basics over time? I know we're struggling with the spread, but I think the same concept applies. Plus, if it comes with winning, you'd think you'd want to keep learning more and expanding and getting better at what's making you successful?
4. I know the question comes up with receivers and how they are less needed and QBs and all that. I personally think Adrian Martinez would make a sick option QB, assuming he can get back to making decisive reads and decisive running again. Running in his strength one he makes the decision. Also think Luke would be dynamic in that role too if he were to pick up a few more lbs first. Still have to recruit elite receivers regardless because you can't run the ball every play for 60 minutes. And honestly, with only about 30% throwing, if you're reliable you're just about guaranteed you'll get the ball every time it's thrown.
