It makes complete and total sense to me. Ekblad has won his cups: it's the perfect time to go to a rebuilding team for the highest payday. Anaheim has a major prospect glut at LD (LaCombe, Zellweger, Mintyukov, Solberg) but only Luneau as a potential top-4 piece on the right long-term. They have a significant need for a veteran RD long-term, and an added bonus for Ekblad is that he would reunite with Coach Q.
