It would be the most expensive TDL rental in recent memory. IMO it’s outrageous if it’s only for 2 months of Lindholm.However the price was not so outrageous. If it were, I agree.
The Bruins have a strong core the next 2-4 years, especially after this trade. Those 2nd round picks likely are traded at those trade deadlines otherwise as well. The 1st is the main asset. Vaak may end up a steady #4-5 for Anaheim but has injury concerns himself. The Bruins have a number of 5-7 defensemen types already...
If you added another 1st it may have been enough for Chychrun who’s locked in for a few more years. Again, if Lindholm is re-signed it’s a fair price and I get it, but if not it makes it difficult to fill other holes in the next season or two.
