If you don't mind me chiming in...the whole problem with tdl is transition time. It takes a long time on average, even for Toffoli paying immediate dividends. It takes a while.
Look at Reinhart in Fla, he was up and down like a whore's drawers with his play for 40 games, now he;s right in there. Then look at Giroux, he's been okay, they still would have won 9 in a row without him.
Bennett, same. Look great sometimes, but up and down.

I get they're pros and have jobs, but it's very unsettling to your personal life.
