I hope I get to watch him again because the game today I'm not even sure he played 14 minutes. When he did play absolutely nothing stood out. Not his size, strength, skill, or oh so amazing skating.
At the draft it was a very questionable pick. He was considered very raw and a long term project.
Playing against his age group, only earning bottom pairing/PK minutes, and showing meh at best I think we can safely ignore this kid for at least 3 more years.
I know it won't change any opinions about him, but to add a bit of context to this post I would like to point out that Sweden is rolling 7 Ds in the tournament. In the game you're referring to (vs Slovakia I guess) the D TOI times looked like this:
Soderstrom 19:19 (20 shifts) -- PP
Lundqvist 17:38 (23 shifts) -- PP
Sandin 17:05 (19 shifts) -- PP
Ginning 15:34 (17 shifts)
Broberg 15:18 (21 shifts)
Bjornfot 14:19 (20 shifts)
Norlinder 12:37 (15 shifts)
This has been more or less the norm, except that Ginning played a bit more than usual. With regards to ice time it is also necessary to not only point out that Broberg does not play on the PP (which you did) but also that Sweden plays a lot more PP than PK
(edit: after 5 GP SWE has spent 44:00 mins on the PP and 24:26 mins on the PK). I have not found any tracking of PP/PK/EV ice times for individual players, but looking at the stats from the individual games and totals I don't think that it is an outlandish assumption to say that Broberg is most probably the most utilised D on EV+PK. He is 4th in TOI behind the three PP D's and 4th in #shifts over the first 5 GP, but it is all pretty even (which was expected by most prior to the tournament): Soderstrom 111 shifts (PP D), Lundqvist 104 shifts (PP D), Sandin 101 shifts (PP D), Broberg 100 shifts.
Regarding playing against his age group I think sometimes it is still good to remember that Broberg is very young. Counting the big 5, i.e. CAN, USA, FIN, RUS and SWE, the only defenseman who is younger than Broberg is Drysdale.
Lastly, I get that you have a strong opinion about Broberg from the get-go since you did not like this pick. Not considering that though, and not entering into another discussion about the draft, "meh at best" is hyperbole. He has been solid, not spectacular or flashy, but consistent. His pair with Bjornfot spends most of the time playing with Swe's lower lines to shut down opposition and that obviously shows. Yesterday he had another good game, even though some say they didn't notice him (I did, but I was actively looking for him, so there is that). He broke up several plays and kept moving the puck in the right direction, not flashy but very effective and a big reason Swe shut out the Czechs. Most of the Ds are very good though, so it is a bit hard to stand out. This is the best D group Sweden has iced for the world juniors in many years, probably ever, and he is still the youngest out of the group.
