The 25-year-old Australian-born midfielder has recently completed a trial with the English League One club and although his time with the Sky Blues did not end with a contract offer, Mowbray insists he remains a player of interest.
"He's left us now but I think there's a potential footballer there," he told the Coventry Telegraph.
"I'm not sure he's ready now or could come and play in our team today. Positionally, he would have to learn a role so I have left it with (technical director) Mark Venus to see what his advisors are thinking.
"He might be too much for us or he might want an opportunity. But I saw enough to think there is a footballer in there and definitely an asset.
"He's 6ft 4, can run all day, passes it nice and simple and he's a brilliant individual. He's a lad who likes football, loves to talk about football and the tactics; 'why are we doing this, why are we doing that? At Seattle we don't do that,' so I like his personality."
Mowbray added that if Coventry were to go after the former Bristol City youth academy product, the West Midlands outfit would look to avoid paying a transfer fee for his services.
"There can't be a fee to pay because we wouldn't be interested if that was the case," added Mowbray.
"I leave all that to Mark really. If he wasn't an option for us financially he wouldn't have been here."
