The Rangers simply don't have the resources to target another established talent at any position unless they're willing to try and upgrade a player by moving him and a prospect. I.e., move Stepan and a guy like McIlrath for a better center. All that does is create a bigger gap between your best at the position and your 2nd best. That's not balance, it's stacking the top of the order.
What the team ought to be doing is trying to buy low. All successful teams have that player that takes a big step forward in order to become an important piece. Colin Wilson was mentioned, who is an interesting example. Alex Burmistrov is another. Both could be options to find that diamond in the rough. Adam Clendening is a very good puck mover who should be ready to crack an NHL lineup next fall. He's had a very steep development curve thus far. Puck rusher who can run a PP. Right handed. The Rangers could do a swap of less-established players to get the guys they want.
AV gives everyone a second chance after he throws them to the media. Some players respond and respond well, while others do not. If JT Miller can't bounce back, I don't see a future for him here. If that's the case, the Rangers should move him for a piece they can use.
