That year Grabner returned a prospect + 2nd, Plekanec returned a 2nd+, Tatar returned a 1st + 2nd + 3rd. A reasonable return for JVR + Bozak would have been 1st + 2nd + 2nd at least, maybe more with retention. We got more for Franson + Santorelli + Polak, hell we traded the same replacement level grinder for a 2nd in two consecutive years.
McDonagh and JT Miller returned a 1st, a conditional 1st/2nd, and 3 ~2nd round pick value filler pieces that same deadline. JVR + Bozak + not trading for Plekanec = 1st + 3 2nds. JT Miller later returned a 1st + on his own. Which team do you think would have been better, one with JVR Bozak and Plekanec, or a team with McDonagh and a young physical 1W/2C? Both McDonagh and Miller had term as well, we'd have them for at least 2 playoff runs.
If Dubas traded Hyman last year and used the return + cap space to rent Hall + Foligno or some other grinder, we'd be better off considering Hyman was a ghost in the playoffs.
I get that drastically shaking up locker room chemistry close to the playoffs isn't ideal, but there's value to be had selling off pieces you don't need for ones you do. If one of Liljegren/Sandin/Dermott step up this year and show they can handle top-4 minutes, Rielly/Holl should be on the table if a contract extension isn't looking likely. Rielly/Holl both bring back 1st+ from a contender with a hole on D and some money to play with in the summer. Rielly out and a Muzzin-type deal (1st + 2nd + 2nd for a #2/3 with an extra year of term) in doesn't make us worse today.
It's not Dubas' thing to let FAs walk, I like that he knows when to cut ties and avoid boat anchors for support players. It's just strange that for all his Moneyball approaches, he hasn't exploited what seems like a market inefficiency that only exists because it's taboo to shake up the room when you're winning.
