I think you've conflated 2 or 3 issues here. Whether Laporte can deal with a skilled attacker has little to do with handling a high press. One is a function of his defending, the other his pass ability or comfort on the ball. Unless you are suggesting he is terrible at both.
And both probably have little to do with his 'lack of caps' as there are worse players who have gotten caps.
That said, I share your sentiment of not been sold yet on Laporte. But so far so good. This is going to be another test for him
No conflating - they were two separate points.
