his best year being 45ish.
His best year was 45 in 70 (53pt pace) and that's with only 9PP points on a disfunctional 2nd power play unit. He's also got 9 points in 15 career playoff games which, while a small sample size, is reflective of his impact in those games if not predictive of future games.
You're welcome to disagree with me but it's not lunacy to think he can get back to the level he was at before Glen Gulutzan came and decided to misuse him. There's a reason the coach was fired and it wasn't just to put a head on the spike for a bad season, it was almost exclusively because of
1) A bad power play that didn't utilize one-timers from forwards, something Brodie could set up from the point if the strategy weren't inane and counter to Brodie's pass-first style of play
2) Systems that are counter to Brodie's skillset and ability to confidently dominate games like no other defenseman on the Flames blue line.
