Is there any correlation between size and regular-season success? Yes, but in some cases no.
Let me summarize this article for you:
What if the problem on defense is because the Eagles draft small players? Could it be? Maybe, if I repeat the question enough. They are undoubtedly small, though. Well, unless you compare the Eagles to similar defenses. But I’ll call them tiny anyway. Does it matter? This small sample size says yes. But not this slightly larger group. Forget it, I’m just going to cherry pick some stats that support my argument.
