brodie last season was one of best d defenside side of the puck amount all d in NHL. This season, i think some fan just really underrate what hes doing to compensate all injuries in the line up. Tanev will do absolutly nothing more than what brodie actually doing, he would maybe help brodie to split defensive mission and bring a secondary weapon but thats it. when your thinking than the greass are greener at your neighboor... thats whats its looking like... and no brodie is not a big hitter but a great hockey IQ. most of the time, big hitter hit to hide some weakness on his hockey IQ and didn't read the play pretty well. yes brodie slowed down at 34 but also the case with Tanev.
for tanev over klinberg, depend what your need is... tanev will not hslp on transition who was a huge weakness last post-season. yes he would help to raise pk and play defensive but with a lack of transition, leafs d will struggling again. so if tanev is the only move leafs making at D, i dont consider leafs as contender this season, simple as that. they need someone who can play both side of the ice.
ps leafs can trade for a rental with intention to resign him long term.
