First of all, if we're talking about the moves when he just got the job, I don't believe those were his moves. Dolan fired Gorton, "installed Drury" and took control of the team for that offseason. Or at the very least Drury had a mandate from Dolan to execute exactly the types of moves he did or he would be the next to get canned.
Since then, I'd also say that the Kane trade was another Dolan move. Made no sense for the team. Plenty of "insiders" have also said that was a Dolan move.
Evaluating the moves he's made when his hands weren't tied, I don't think there's as much reactionary as you say. The worst move was probably to lock up Zibanejad with a buyout proof contract, but he was nowhere near this downtrodden when he got that deal. It probably wasn't going to age well. It would've been hard to think he'd collapse this quickly. There's also been plenty of restraint (the two years we made the ECF he only nibbled around the edges at the TDL and didn't give up significant futures, he also didn't commit long term to Lindgren after his bad year, took the "wait and see strategy, which in hindsight looks very smart).
There's been plenty of measured decisions in there. I think if there was a reactionary move it's probably coming from Dolan, but the team is playing great right now, so there's no need for that. And Dolan is probably preoccupied with the Knicks right now because they're better than the Rangers for the first time in forever, so I doubt he's getting involved right now to trade for Miller.
