There’s absolutely no way for you to know that. There are plenty of D who play effectively in this league well beyond 35
Its a pretty much guarantee based on other comparable players
Ryan Suter --> elite #1D who fell to good top pair to an unplayable player on dallas
Giordano --> we got as a great 4D who by this year is retirement worthy
Brodie --> fell off to a bottom pairing defenseman
PK subban
Ryan Mcdonaugh
etc etc,;
Tanev isnt a top end d-man who will be able to provide offense when his defensive game falls off.
Tanev has been injury prone his whole career, gives 0 puck offense and isnt a physical clearing the net type of player
He would be a good #3RD add sure. At 2 years 2-3M that is a value add and winning move
He cant be a top 4D for us
XXX - XXX
Rielly - XXX
McCabe - Tanev
That is a great dcore
Marner --> Need to become a 1LD or 1RHD
2RD --> Pesce, Montour or Skeji on their offside, Roy in the worst case scenerio
Leafs adding a filler piece like tanev to the same core 4 who are 15M overpaid for their repetitive underperformances in the playoffs wont change anything for this team
Givinv tanev 3.5M x 6 or whatever is rumored wont help us
