I think ideally you just want a bunch of guys that can get open. That's really all you need. Wear down defenses. You can totally have an offense based on the principle of 'death by a thousand cuts'. If your receivers get open, even for just 6 or 8 yards at a time, but consistently, you will score. It can lead to defenses getting frustrated and taking gambles that expose them. It can lead to opposing offenses taking gambles because you're using so much clock. Honestly, if you can do it, it's one of my favorite offenses to watch.
