At the surface level Focht's production does look like it stalled, but allow me to add a little context.
Calgary as a team was worse offensively this season, and they played a more defensive system to make up for missing key offensive players like Zamula + Malm (got traded away in January and suspended for not reporting lol!) for extended periods of time due to injury. The PP especially suffered without Zamula, and Malm. The teams goal for, and goal against dropped vs last season, and the PP went from elite in the WHL to average. Here are the team stats for reference,
2018/19 - 68GP 255GF (Rank 7/22) 240GA (Rank 17/22! ) PP% 27.9% 68/244 (Rank 2/22!)
2019/20 - 64GP 219GF (Rank 10/22) 201GA (Rank 10/22) PP% 21.8% 42/193 (Rank 11/22)
Focht himself saw his PP production drop from 2018/19 to 2019/20 by nine points, but his even strength offense actually improved. here are his PP/even strength stats from the last 2 seasons,
2018/19 - Total 68GP 26G 38A 64Pts 0.94PPG - PP ( 9G 19A 28Pts) - SH (1G 1A 2Pts) - Even (16G 18A 34Pts 0.5PPG)
2019/20 - Total 61GP 32G 24A 56Pts 0.92PPG - PP ( 9G 10A 19Pts) - SH (0G 1A 1Pts) - Even (23G 13A 36Pts 0.59PPG)
So as we can see here Focht's production dropped mostly if not entirely due to Calgary's weaker PP, not due to his offense stagnating/regressing like his PPG would indicate, and Focht probably would have been PPG+ if the PP hadn't regressed. He actually took a big step at evens when it came to goal scoring, going from 0.24GPG to 0.38GPG, and scoring 72% of his goals at even strength. This season only 34% of his point came on the PP, and 64% of his points came at evens! Last season that number was 44% on the PP, and 53% at evens.
Now with all that said...I still would've like him to step up more offensively, and his production doesn't inspire a great deal of confidence going forward, but given his improved two-way game and the goal scoring ability...I feel we still have a potential bot 6 C who has PK upside. He actually reminds me a lot of Brandon Sutter in that he's a solid goal scorer, but is an average playmaker. Ultimately, we'll have to wait and see how he does in the AHL, but for now I'm personally OK with his production last year.
