Brough, a livewire half-back, is also Scotland captain, and was the 2013 Man of Steel.
“His performances speak for themselves, in regards to what he can do on the field,” said Anderson.
“It’s a credit to him and his durability to be at 31 years old and reach 400 games – those are the kind of milestones you hit as a much older player.
“He’s a very durable player is Broughy. He very rarely misses games, which is a credit to him and he’s tough and vigorous in what he does.
“His level of performance on the back of it is not questionable; everyone knows what he’s capable of.
“I think he’s improved and there’s still ways to improve as well. The last couple of years he’s been our captain and that responsibility has maybe calmed him down a little bit from what he has been in the past.
“The 400 mark is a fair effort, and these are things you think about once you’ve retired.”
Brough himself reacted modestly to passing the imminent career milestone.
“I didn’t expect to reach that mark when I first started out,” he said.
“I’m pretty pleased with that and it’s an achievement under my belt that I didn’t think I’d get this quickly, so I’m really happy that it’s come around already.”
