nyquist has career high individual point % (% of points player gets for all the goals his team scores), save for his short stint in 11-12 and career high on-ice sh%. both of them are going to regress towards mean, sooner or later.
bobby ryan, mathieu perreault, nick foligno, kris versteeg, drew stafford, teddy purcell, clarke macarthur, milan michalek, tomas fleischmann, dustin brown, tuomo ruutu, brooks laich, r.j. umberger, brad boyes, rene bourque, jason williams, alexei ponikarovksy, jussi jokinen, jiri hudler, jiri stempniak, ryan malone, chris kunitz, radim vrabata, micahel ryder, scott hartnell. all wingers (some played also C) and scored between 0.55 and 0.65 ppg from their age (as of feb 1st that season) 25 to 29 seasons and had those years postlockout. and all of them, except the last 4, saw their ppg decline dramatically and/or became washed over the following 5 years. granted, some haven't finished that 5 year period yet and some are still season on their age 31 season but on the other hand, it's already looking bad for them.
chris kunitz was traded to the pens and spent most of the next 5 years playing with sidney crosby. michael ryder maintained his ppg and NHL in general valued his contributions so much that he spent his age 30-34 years playing for 4 different teams. and for relatively small salary compared to his contributions, just like kunitz. hartnell and vrbata didn't see a big bump in linemate quality and maintained their scoring prowess as they aged.
most likely nyquist won't maintain not only his current ppg this season but one he's had over the last 5. if he gets paid about the same and it doesn't have NMC and is 4-5 years i'm ok with him coming back after he's traded at TDL. 0.6ppg wingers who don't play complete game aren't that hard to find that keeping and extending him is the better option than getting the trade assets and not locking 30+ year old to long-term deal that he most likely won't live up to. even if he'd be unwilling to come back in FA after being traded. don't even want him back if the contract would be something like 6x6.
we're soon or relatively soon going to get rid of the bad contracts holland signed between '13 and '16. let's not make more.
