I don't like to join in something that is obviously just pure rumour, but even if Smith was to leave, do you really think we'd replace him with Lowes??...
The one thing that Simon Moran will have definitely learned in the last 5 or 6 years, is the invaluable need for a quality coach....You can sign all the top-notch players you want, but put them in the hands of a numpty and you will forever under-acheive.
Smith has been excellent, but if he was to leave, I'm sure Mr Moran would make sure he was replaced by an adequately qualified coach.
