interesting, there is likely an updated analysis of offensive coordinators,
looks like atlast when this was written, many head coaches were also calling the plays, some very successful teams.
not sure which OC available now, but I guess they do need to be familiar with offense similar to what Texans run.
And it would be nice to see some due diligence in choosing the new OC if needed.
