That's high praise from a man who knows what it takes to play in the Scotland engine room, as well as lead Celtic to scores of trophies.
Miller is only one behind his dad Lee in terms of Scotland caps already.
Seeing pictures on the wall and his dad's cap serves to inspire him, but having a family member who knows the ups and downs football can bring must have helped mould him into the calm and confident player he is.
Miller was given an example of how things can trip you up when he said he wanted to be Scotland's best player in a few months' time back in March.
The reaction was over the top, a case of Miller slightly misspeaking, when actually showing confidence and ambition in the unforgiving world of football is nothing to be ashamed of.
The teenager now has an interesting summer ahead.
With his deal at Motherwell running until the summer of 2026, the Fir Park club are likely keen to cash in on another successful academy player before his deal runs out.
The intrigue around his next move will intensify as the summer progresses.
Will he follow the lead of so many other Scottish players and ply his trade abroad?
One thing is for sure, he will have options.
"Motherwell have given him the opportunity at 16 years old to go and showcase how good he can be and they will go and reap the benefits within the next couple of months if I'm honest," Brown said.
"I think, teams are now looking at him seeing assists as an 18-year-old, and now they'll see how high he can go as well - so people will want that in their team."
Not that you'll catch Miller talking about a move. When asked about what's next for him his response was simple.
Holiday. Pre-season. Go again. With the depth Scotland have in midfield, it is far from certain whether Miller will see lots of game time when the world Cup qualifiers start.
However, if Clarke does call on him again, your best bet would be to back him to be ready to take on bigger challenges.
