Oshie didn't regress? Are you sure?
Oshie has just one even strength goal this season. Remember that falling down poke goal against the Penguins that Locker went wild for? That's his only one. He only has four primary assists at even strength as well. His points/60 at even strength are only 1.45, sandwiched between Garnet Hathaway (1.68) and Richar Panik (1.33) among the Capitals forward ranks. His individual shot attempts are the lowest they've been since he joined Washington. In 15-16, he was attempting 12.19 shots/60, now it's fallen 24% to 9.83. He has a negative penalty drawn/taken ratio for the first time since joining Washington, and only Hatheway, Down, and Panik have fared worse in that category among Caps forwards.
He's 34 years old, counts $5.75M against the cap, and still has four years remaining on his contract. Is he going to completely implode tomorrow or the next season? Hopefully not. But he's already already turning into a sheltered offensive zone and powerplay specialist. His on-ice numbers and expected goals are still good, but that's because Laviolette is starting him in the offensive zone 77% of the time.
I love TJ Oshie. He's a heart-and-soul guy. He's a warrior. I wish he could spend 10+ years in Washington. But the years I want are those from before he joined the Capitals, not the ones as he approaches retirement. This is a win-win opportunity for both Washington and Seattle. The Capitals dodge the worst years of Oshie's contract, and the Kraken get their home-town kid, marketable face of the franchise, and likely captain.
