So far, the Knicks offseason has been filled with great news. They traded for Mikal Bridges out of nowhere. Then they eased everyone’s worries by re-signing OG Anunoby before he reached free agency. And just last week, they had a very successful draft by grabbing a high-upside wing in Pacome Dadiet, then picked a pair of upperclassmen in Tyler Kolek and Kevin McCullar Jr. who should be able to crack the rotation and contribute in their first season. But this morning, the Knicks and their fanbase were hit with a gut punch as it was reported that center Isaiah Hartenstein would be signing with the Oklahoma City Thunder for $87 million over three years.
