Don't think Lysell is the next great one and not overrating him. He is just the only top 6 prospect Boston has so they should be reluctant to give him up. It's a fair ask that he be included in any Hertl deal. Pastrnak was drafted 25th. The chance that Lysell could POTENTIALLY turn out anywhere close to him is why San Jose wants him in any proposed deal and why Boston should say no and move on from Hertl.
