He wasn't gifted anything. He was played in the Flames' bottom 6 (with very little PP time) almost exclusively; the only time his ice time consistently went above 15 min/game was in 2013 after the trade deadline, when the Flames had a ton of open roster space. He was also frequently scratched and shipped back-and-forth between the AHL and NHL like half a dozen times.
Baertschi was/is an imperfect young player, but he still got a bit of a bum deal with the Flames. Every organization has its golden boys and its black sheep, and Baertschi appeared to be a black sheep when it came to Hartley.
He was gifted his time up during Feaster's tenure. What happened when Feaster got axed? Hartley sent Sven down to the AHL. There was widespread speculation that Feaster was forcing Hartley to play him, and it was indirectly confirmed by Hartley booting him back to the AHL almost immediately.
Since then, he wasn't gifted much. There was a couple of call-ups where (I thought) he didn't deserve to be called up to the NHL ahead of some other prospects that were actually doing better than him in the AHL, but I am sure the Flames were wanting to see how Sven did in the NHL and plan accordingly (especially last season, seeing as it was his last waiver-eligible season).
I completely disagree he got a 'bum deal' with the Flames. Why? Why would Hartley or the Flames' organization want to give this prospect a 'bum deal'? Why promote guys like Jooris, and continually call-up other prospects like Granlund ahead of him? Seems to me that they were simply better players in the AHL and were more deserving of the call-ups, and they also performed better in the NHL as well.
I think Sven is a longer-term project with great upside still, but I just can't fathom how people are still writing some sort of narrative that he got a 'bum deal', as if the Flames mistreated him. If anything, I think the Flames unfairly placed him ahead at times (especially during Feaster's tenure) of other prospects on the call-up list.
I think some fans see the super slick plays he makes now and then (actually, quite highly skilled plays, like his behind the blue-line pass through the neutral zone perfectly flat and on Byron's (or Jooris') stick in full stride - thing of beauty for sure) and think he has an NHL game. Loads of prospects with even more skill have bombed in the NHL. He hasn't busted yet, but right now there are more questions than ever regarding if he can translate to the NHL or not. He is a very good talent, so it will be interesting to see if he gets it together or not, but there are some big question marks at this point in time. It had nothing to do with the Flames giving him a 'bum deal' - not when you see other small(er) and skilled prospects playing 200ft games and buying into the system completely. What is the narrative around that? Simply that Baertschi ran over Hartley's dog or something?
