Porter: “He’s not an elite athlete and he’s not the fastest guy, but he’s one of the most technical players I’ve coached and one of the smartest players I’ve coached. We built our style around possession and there is no one better out there when it comes to possessing the ball.”
That pretty much sums it.
He is technically flawless and seemingly ambidextrous. Note how Caldwell always passes with the correct foot, keeping his body between the defender and the ball. Most professionals cannot do this, mostly striking the ball with their dominant foot! Efficient technique compensates for moderate athleticism, as does superb endurance.
Also to Caldwell’s credit is excellent tactical awareness.
He will likely enjoy a solid professional career. If he so chooses, I think he would make a phenomenal head coach someday.
