I was offered a trade recently

His: Larkin, Konecny and 3rd round pick

My: Keller and a 2nd round pick

The catch is once the season is done i would send Fleury to him for Howard.

It would leave me with Talbot and Howard as possible keeper goalies along with Larkin, Teurovainen, Hischier, Zibanejad, Spurgeon, Trouba, Kreider, Strome, and then either Schwartz/Pionk/Klefbom/konecny as my last keeper.

Is this trade worth doing and if you think it is who should my last keeper become?
