What they are referring to is that for an OLman there are a couple of critical things that have to happen (aka: leverage and control) - 1) they have to get underneath the d-lineman and pop him up 2) They have to bend their knees and set a good balanced stance 3) good hand/foot work and never stop moving. We fail at all three. If you watch 80% of the time we are high up (the D got the underneath == control), they are leaning over and extending (making them off balance and easy to shuck, drive back), and they don't have solid foot/hand work (allowing separation, push back). Offensive line coach is a technician (Saban talks about this in that oline is very technical and you really don't hire them for recruiting or other jobs). Not to mention there is a ton of communications and blocking schemes that each position must learn and adapt for each defense they encounter. If you watch when an offense comes up to the line the oline is talking and pointing and/or gesturing down the line. This is critical. Its almost like a very sophisticated dance. You really need to have a top level technician coaching them. Or you need 5* Jr/Sr filled line across the line. Just my opinion, but really don't see Searles getting it done. His success has come when he had 4 & 5 star Jr/Sr talent which hid a lot of his coaching issues.
