Dunno about that.
I'd say one of Stewart's main problems is that he isnae suited to what was, formerly, default formation 4-2-3-1.
To me , Stewart's an inside forward, drifting wide then cutting in.
The three in behind was ideal for McGinn, for me he could've played any of the front 4 in that formation.
Dinna get me wrong, in terms of quality/ability, there's nae comparison, but it's nae a like for like thing.
