Quoting: CheechYou
If you'd actually watched him play this season with the Sharks, you'd know that he's been excellent even against top competition and has absolutely been a pleasant bright spot this season.
Granlund's legit good. He was God-awful with the Pens, yes, but he's flipped an absolute switch this season.
By what metric are you referring. All the stats I can see show him as a below average player even among his peers on the Sharks.
(All stats 5v5, all comparisons are vs forwards with 500+ min)
Expected Goals per 60: 0.54 (3rd worst on SJ, 11th percentile)
Goals per 60: 0.39 (3rd worst on SJ, 9th%)
Points per 60: 1.38 (2nd best on SJ, 26th%)
Faceoff win: 49.1% (2nd best on SJ, 62nd%)
Corsi: 41% (Tied worst on SJ, 4th%)
Expected Goals against per 60: 3.42 (2nd worst on SJ, 0th%)
Shooting Talent Above Average: -4% (4th worst on SJ, 31st%)
Created xgoals: 4.5 (2nd worst on SJ, 5th%)
All of the individual stats above are very similar to his career numbers and numbers with Pit last year.
His PP numbers are also not good, though they are better than with Pit last year.
Granlund appears to be a worse version on Monahan, who did (surprisingly) net a 1st. So it is possible someone will overpay but based on his stats, a 3rd would be an overpayment for Granlund.
Side note, great username. One of the best on this site.
