Did Liljegren play on the top power play unit this year?
Yes. Despite the what some people repeatedly say on here.
Liljegren played the first 10 games of the season on the PP1. There is zero doubt about this.
Subban and Nielsen split PP2 time over that period of time.
Rosen didn't get PP time over the first 10 games, but with 7 ES points and another one SH, he pushed himself on to the PP starting with game 11. Sandin, who missed the first 8 games of the season started getting PP2 time during game 12 (his 4th) after putting up more ES points in his first 3 games than Liljegren had (in 11 games). Liljegren was injured during the 19th game of the season, but had effectively been moved off the PP after 11 games. Some might say that was so he spend more time concentrating on ES and PK, but both during his first and second year the PP was not very effective with him on it.
When he returned from injury he played on the PP2 when Rosen was injured and then called up to the Leafs (which was a significant chunk of time). 40% of his points came on the PP which is a high percentage but mostly an indicator of how lackluster his ES production was - 9 points in 43 games (only LoVerde was worse in ES PPG)
