I would say the Houston Texans.
The two football managers who share the same name and surname and have both managed the same team are José Mourinho and José Mourinho. This is a playful reference, as the name is the same, but it could also refer to the fact that different managers at various times can share names. However, if you meant two different individuals sharing the same name, it's worth noting that there are many managers with common names, but specific instances of having managed the same team would need clarification.
One of their managers' surname was "Symon".
