It's really a good example of what Aubie 16 said the other day about Leach's, Franklin's (and his protege Neal Brown), and Dana Holgerson's systems being "totally different. They're the same offense, being called by different play callers with different talent sets. It's Meyer's offense, being run by Addazzio instead of Mullen (who helped Meyer create it), and without Tebow. It aint working quite as well as it has in the recent past, but they're not going to abandon it because the fans think they should.
Meyer's passing game has never been regarded as especially ingenious. He had Leach in during the off-season to consult n the passing game, and I've seen them run a few plays that look familiar to Leach's offense, but can't honestly say they didn't have them in the playbook already.
