Yes it's praise. You are completely and utterly missing the entire point, choosing to instead focus on the opponents and create a narrative that's not there as if I'm somehow suggesting he only plays well against shit opposition.
Seeing as you clearly need me to spell it out for you, Rodri excels against teams that play long ball football, it plays to his strengths, and hides his weaknesses. This isn't news, it's been the case since he signed for us, it's not even a debate. The most ardent of rodri haters and the biggest Rodri fan on the planet would both agree with that.
It's like saying Jamie Vardy plays his best games against teams that play a high line. It plays heavily into his strengths with his pace and movement behind, similarly for Rodri, long ball teams are bread and butter for Rodri with his physical attributes and aerial dominance.
Every time we play a team like that, he's invariably in MOtM contention, Burnley are the last remaining true long ball team in the league now and every time they play us with the same tactics Rodri puts in a top performance. Chelsea inexplicably played like that last month with their lump it to lukaku approach and Rodri licked his lips in disbelief after being given the run around by Kante last season, Sheffield United did it last season too and Rodri was superb as expected.
And no, before you say it, that isn't to say his only good games are against long ball sides.
As for him being unfortunate the league doesn't have many Burnleys left, that's simply to say if he had come in with Pep when the league had at least half a dozen teams that would play like that with the likes of Stoke and even capable sides like Everton adopting those tactics and causing us big problems, he would have been a much bigger asset to us with those specific qualities than he is now because fewer teams play in a manner that require him to use them.
