I've long thought the footwork cliche is so overrated. I'm not saying it doesn't matter, so please don't attack. I'm just saying when watching today's NFL and how offensive lines change yearly for every team - clean pockets where mechanics and footwork were paramount, hardly exist.
These QB's throw off balanced and on the run, most of the time. Now if there's some way to improve footwork on that, fine. 5-7 step drops, hop hop and throw, happen more rarely.
