You do realize that O'Brien's offense already relied on spread concepts since he was with the Patriots right? Do you want me to find articles about that? The point was Watson has been the only quarterback he's had so far that has been smart enough to manage to run his offense. You also by the way just echoed what I already said with that ringer article. His pre-snap motion is the major change made to the offense. So adding like 30 plays of RPO and designed quarterback keepers doesn't suddenly make it a new offense tailored to Watson. Its just an added wrinkle to make defenses think about something else. Those hundreds of other plays still are within what O'Brien already was doing and trying to do, while failing badly might I add, with his previous quarterbacks. He was chewing through quarterbacks like they were the Cleveland Browns...
