I wouldnt give up Liligren anymore man. He's way too valuable to the org, and will be playing top 4 min next season, on a cheap contract. There will be other options available

You're right. Leafs have been looking for cost efficient young Dmen. Sandin and Liljegren have been paired and played well. In what world world would the Leafs give up all that for one year of Guentzel?

Yeah I've imagined Sandin and Liljegren staying together in an offensive role with Muzzin being used as a veteran D presence with Topi. The question will be how effective are Rielly - Brodie are in 2+ years

Um, no. If you want us to take on that Mrazek contract, you pay us. The Jackets have no need for an additional goaltender (heck, we're trying to move Korpi as is to make room for Tarasov), and have less than zero interest in paying an injured backup almost as much as our starter.
