When was the last time Skinner played in the post-season? And 2 out of 3 of Patches post-seasons he put up solid numbers (11 in 17, 7 in 11). Patches put up 60+ in 4 of the past 5 seasons and Skinner put up 50+ in 3 of the past 5 and had 49 last year. Silf hasn't broken 50 in his career. Silf has the best defensive game out of the 3 of them but they're clearly more proven offensive players. Sure players like Silf have pulled more than a 1st in the past but you have to take into account the market too. Not saying Silf doesn't end up pulling more than a 1st if he's available but I think a 1st is fair value. Also, I stipulated "Silf's value is a 1st until extended" so saying that his value increases if extended is kind of irrelevant.
Patches has been to the playoffs four times. Two out of four were productive. Skinner having no playoff experience absolutely plays into his evaluation. Silfverberg's ability to shut down elite players is more than just having the best defensive game out of the three. He has 39 points in his last 44 playoff games. He has been a reliable performer in the post season over the years on both ends of the ice. Teams typically bring in rentals for the playoffs or in the hope to sign that player long term. Even if those other two players were coveted more than Silfverberg, which I doubt, there are 16 teams headed to the playoffs and all of them will be looking for upgrades. That there are two other competitors on the market doesn't drag down Silfverberg's price at all.
