To the FrustratedFinFan, I use a 4-3 d and it works fine for me and I have beaten people who put 9 or 10 guys on the LOS, here's what I do, my OT's block outside looper's, my OT's are put on ttc bases that make small tight loops and I don't use ITZ dials, what you have to do is find two strong ttc bases that makes small loops one for the left side and one that loops right it would be good if the bases have some speed, I have found they do stop the outside blitz, just like in the NFL, the OT's job is to stop the outside blitz.
Now, if you are planing to do the spread offense you will need this type of OT's I was taking about and if on the right base, they won't run into your WR's but take out the looper's, that's just my two cent
