They have lower peaks.
Toews is the only player out of the three with individual hardware and a Selke ain't much to brag about...CS is nice but below a Hart and rocket.
If you wanna use just raw numbers against Perry it isn't like Toews is that great, unlikely he even gets to 400 goals or 900 points.
Getzlaf was Perry's longtime teammate, very solid player, decent bit under a PPG, just one cup.
Tavares is interesting, he will finish his career around close to 600 goals and 1300ish points or more but he has as of now zero NHL team success and international not that great didn't score a single point in the 2014 Olympics before getting hurt.
Don't get me wrong I think every player will make it, I just don't get the Perry being a weak argument with how the hall is these days
