Totti already shown why this argument is dumb. You're saying that Alonso is one of the GOATs with this stat based logic.
It's too simplistic. There's not a stat for how many opportunities we miss from Davies not attacking his man, for how much width we lose out on which affects the ENTIRE attack from back to front, for how much momentum is not capitalised on by having no threat from anywhere other down the middle which can easily be packed etc.
He's posting a question bringing up a point, so no, he's not saying anything about Alonso.
However, it is not unreasonable to say that Alonso is a great wing back for his club based on his stats, despite the fact that he at times doesn't look like much of a footballer. In football it is more important to produce the goods than to look good, which is one of the reason Kane is about a million times better than Wellbeck, why Crouch was a decent attacker and Long is shit, why Alli is such a fantastic player, why Townsend never made it with us.
Townsend was flashy as fuck, had a monster of a shot, but never hit the target and didn't learn how to efficiently use the ball.
Davies and Trippier may not look flashy running down the wings, but they more often than most fullbacks have a thought an aim and/or an ability to hit an attacking player with a cross, whereas Rose and Walker more often than not just rushed towards the line and knocked the ball in with little control or aim to it.
