midline out of split backs?

We tinkered with it one year in two-a-days and tried it week one. It just doesn't fit the split back system well in my opinion. In order to hit in the middle, the split back has to lateral step and get on line, which took away from the quickness of the play and added the dimension of how far to step laterally which created inconsistency. It took time for our backs to learn the body control of stepping laterally and then getting immediately vertical. Most of them drifted off path early and although we thought we had it mastered, when competition came we drifted again. Perhaps I was too impatitent to stick it out, but I felt like we would have to work the play so much that it would take away time from the true split back scheme. I have actually gone away from the split back because the midliine is such a good play in our little part of the world (nearly everyteam we see runs a 3 tech). Not saying that it can't be done out of split back, but the trial and error here was not successful.
