I have different view on tactical brilliance. What you describe in my term is only positional versatility. Why the different?
Tactical brilliance in my view is ability that can switch role completely. Role here is not mere position, but duty attached to it. Let take Iniesta as example. During EURO 2008, he was a wide playmaker. In Barcelona shirt in later year he was the third midfielder. There was a time he was the assister (Pep reign), but there was another time he had underwhelming end product stats, while his role was to focus on supplying the ball to the front line &a let those do their thing (talking about Henrique reign)...
Perisic is versitle that he can play different positions. However, his play is similar thus his role is limited into stretching the defense by running in behind, taking on his man, causing havoc... He finally found his best position as previously he was an average forward, wide and central.
There is a thin line between versatility &a tactical brilliance but it's there. Rooney was thought to be able to play different role, but in the end as time prove, he was to fill the position than being great in those different role, thus being tactical brilliant. Similar can be said about Gerrard. Iniesta can be a great wide playmaker &a he can be distinctly a great third midfielder playing further from final third. He has the tactical mind for it. Big difference for me. Scholes who some people for a period keep reference for Rooney's change of position, is another case of tactical brilliance. He can play to good level behind the main forward. He 's competent in 2 men midfield. As deep play maker, he can compete with the best. Being shunt left during EURO 2004 didn't matter. He did more than just fill the role. He actually owned it from unfamiliar wide play maker role.
