Thinking of making adjustments ot our blocking schemes

We have always utilized combo blocks whenever possible but I am thinking about going away from it, at least to an extent. This year we went to 3 foot splits for the obvious reasons that a veer team would. This made it very difficult for our linemen who were chipping up to LB's to make the chip and then get to the LB before he flowed over the top. For that reason I am thinking about changing some things within our blocking scheme. Here is my idea. Lets say we are facing a 44 stack defense with a 3 tech. DT to our strength. Instead of asking the OT to chip up to the LB I am considering just telling him to use the old method of taking a path to where the LB is going to be, not where he is pre snap. This would basically guarantee that he would at least get in the way of the flowing LB. Obviously this will make it difficult on the OG b/c he would now have to reach the 3 tech, or would he? I am thinking of just telling my OG to down block on the 3 tech in an attempt to drive him past the hole. Our RB's would just have to be instinctive and be ready to make a slight cut when they hit the LOS. Im sure this would often result in our veer hitting inside the 3 tech but I can't see where that would be a problem. In a nutshell, I am thinking about using angles as an advantage instead of comboing. What do you guys think?
