At a number 9 pick, in exchange for Schneider, I think Horvat was indeed expected to produce, probably 2nd line centre stats: 15 goals and 30 assists = 45 to 50 points within 3 years. Why else draft a centre at 9?
Baertschi is actually the long-shot. A placeholder as Alf says, quite correctly. As only a second round draft equivalent, he could be lost with little upset.
Although Bo can do more of everything than Baer (including scoring), Baer is in a particularly precarious position because without scoring he is not worth keeping. This was true of Nic Jensen, Cody Hodgson, Linden Vey, and even Jordan Subban. As well as FA signings like Vrbata and now Eriksson. The management of any organization expects at least half of their forwards to score on a semi-regular basis, and in the case of 1st rounders, even more so. If players are soft-ish, not particularly good at blocking shots, disinterested in protecting team mates, don't play well in the playoffs, etc., they become even more expendable. (As is the case with half of the Canucks.) Going forward... and assuming this bunch don't keep getting rid of second round picks -- and begin to move assets for more 1-2 round picks (Hansen, Tanev, maybe Edler, Miller and even Markstrom) -- we won't recognize this team in 3 years. Baertschi will probably not be here, nor will some other "regulars" we think are part of the future. Aside from Horvat, Virtanen, Boeser, Tryamkin, Juolevi, and Demko and maybe Sutter: all the rest will be new players.
You do have a valid point about how Bo has been used: and that is, not well. Virtanen has not been handled well either. This team seems to have no idea what to do with young players. Bo gets the 2nd and third tier wingers only. He should be getting time with Hansen and even Daniel. He is the center of the future and already one of the team's offensive engines.
