Nah, if history has proven anything it's that Kravtsov and Andersson aren't NHL players and that those picks just weren't the right ones. Andersson has been with LA and now MTL as long as he was with the Rangers and he's actually played less games. Kravtsov had an "out" and has used it three times instead of redoubling his efforts to become an NHL player.
They were bad choices, in hindsight. Tough to make the call in the moment. I really didn't have a problem with the Andersson pick at the time because I thought, at worst, he's an everyday 3rd line center in the NHL (and said so at the time). That never materialized. I never liked the Kravtsov pick. Laf and Kakko were picks that every team in the NHL would've made.
Lafreniere and Kakko still have time. The question is if the Rangers will be patient enough and have enough common sense to let them develop.
