Thank you all for your comments. All very helpful.

While Bogosian will be treated Tanev will play, in the second half of the season they'll switch places.
A team can never have too many RHD. Yup both Tanev and Bogosian seem to injury prone. What about the value of the trade, is the talent exchange fair?

And why does Columbus need yet another LHD to go behind Werenski, Murray, Nutivaara, Kukan and the Russian we just signed? Also we probably won’t need the cap space this year with Duchene, Dzingle, Panarin and Bobrovsky not likely to be back.
OK, you know your team better than I do. I buggered, I was lazy and only looked at CF for Right Left. I did not see Murray among the LTIR and only Werenski, Kukan and Harrington were listed as LHD. OK, then that trade does not work, my bad. You also know your team, I would have thought clearing $2,900,000 next year and $5,900,000 the next 3 years would help sign at least 2 or 3 of the players you mentioned. I know Murray is injured, I guess he may be ready to come back soon. BTW, about 25 year ago Torts was in the Buffalo system and being groomed to be Muckler's replacement. I always root for the teams he is coaching, he is one of the best. We lost him when Management decided to make a publicity move and keep Ted Nolan and fired Muckler.

Easy no from Toronto. Yes the leafs get cap space but nothing besides a late first to show for it.
I will not disagree with you. I saw a similar trade by a TML fan
