Disagree. Some players have a certain knack of causing Andy problems, others rolling over. Sure, ultimately the H2H means nothing, but it does give a general idea how the other guy usually fares against Andy (the likes of Wawrinka, Raonic, Baghdatis seem to play some of their best stuff, others like Lacko or Dolgopolov never really seem to play well, Simon too) and can be interesting to look at or reminisce.
Dosn't matter. The better player is and will always be Andy against those who seem to cause "problems". It is solely depends on Andy and how's he feeling on that given day. The first tire of players will make it more competitive for sure, but doesn't mean they are going to win it as well. A few times yes, but most times it's in Andy's hand.
