Blocking logic on undercenter jet sweeps needs to be revamped

On every undercenter jet sweep, either the defense end or corner on the side the jet sweep side is going to is completely unblocked. More often the line tight end completely ignores the defense end lined up  over him & splits between the tight end and offensive tackle. This has been tested against 3 and 4 defensive linemen sets and On every underwent jet sweep, either the defense end or corner to the jet sweep side goes completely unblocked.
