You can't completely ignore OVR if you want every edge over the other guys. Paying attention to OVR, and picking up a guy with inflated OVR, may allow you to trade said inflated guy to some other owner who doesn't look deeper, allowing you to obtain better value in a trade. Some of you will call this trade rape, but when you trade a 88 OVR guy for a 80 OVR guy, and you are getting the lower OVR guy (but better ballpalyer), it is just good ownership.
