Has there ever been a multiple grand slam winner with such a limited dimensional game as Stanislas Wawrinka? He is pretty much the epitome of hit and hope tennis with lots of power. When it works, he can sometimes look unbeatable but when it doesn't, he can look like a player who is way below average.
His limited game is the reason why he'll never win Wimbledon.
First of all, you're underselling Wawrinka's game. Yes, it's built on power from both wings, but he's added to that game which is why he improved as a player.
1. His CC FH angled shot was rarely used/effective when he was younger but has become a weapon. He doesn't just hit it as hard as possible, but with touch and dexterity.
2. His BH CC angles have always been good and aren't an example of bashing.
3. His NET game is underrated. His ability to sneak in and close points especially with the BH volley after crushing a FH CC have helped him win his slams. He would not have won his slams without this ability.
4. He improved his serve out wide on the deuce court. This is not s power serve but rather one of precision and skill. He's not really tall so that serve isn't easy to execute.
5. He improved his movement and return enough to give him chances to hit his thunderbolts. A power hitter can ONLY HIT what he gets to and a player who can't move well enough to get into position will never get to hit a lot of power strokes. By the mere fact that he gets to hit so many shows his improvement there.
REASON WHY HE PROBABLY WON'T WIMBY
1) His BH isn't as effective as it has a longer windup and you don't get that time on grass. His return, while improved, isn't good enough to get him enough chances against elite players.
So, yeah, you could say it's his "limited game,"but then you could say that about everyone. Most slam chamipons have done a few things really well that when they really work added with some luck, they can win a slam. People like to compare players to a Federer or someone who has more paths to victory and game than just about everyone, but he's an exception and it's why he's been able to stay on top for so long. Same was true of Sampras.
