I think the chemistry aspect is a little overblown in terms of trades. They obviously arent trading any major pieces off the NHL roster, if any at all. Drury can also look toward guys who have a familiarity with Gallant, or some of the star players so its a more seamless transition. Ideally they add 2 forwards that bump McKegg/Gauthier into being healthy scratches
The Rangers in 1991 traded Kevin Miller to the Red Wings for Joey Kocur. The Rangers weren't a great team but they were leading their division at the trading deadline. Neil Smith made that trade and the team basically lost every game left in the regular season. Pittsburgh won the Patrick Division. Chemistry is important. It all depends on the results. Miller wasn't a great player but he was a key player on that team and the Rangers traded for a washed tomato can with two bad hands who couldn't really fight anymore.
The Rangers need better players than Hunt, Gauthier and McKegg. Those players makeup 1/2 of their bottom six. People are complaining about Gallant. He should be one of the three nominees for the Jack Adams looking at some of the forward options he has at his disposal. People were complaining about Rooney playing in OT against Boston or Detroit. He doesn't have that many options. He could have been sending a message to Drury. Get me better players.
