There were multiple times throughout tue season where Neal took responsibility for his play in interviews. This is literally from the first article I found:
Gilbertson: Flames’ Neal vows to be better after disappointing first season with Flames
Everyone here knows that Treliving often uses a lot of words to say nothing of substance and talks funny when it comes to discussing specific rumours. But I've never suspected him to lie about a team or person's character traits, like when it was called into question after the Ducks sweep.
And honestly, it's not like Lucic was going anywhere if we decided to give Neal another shot this season. He wasn't going to magically put it together and return to his Bruins form this season. I think it goes much deeper than the possibility of getting another Brouwer where something was said in the summer.
We're seeing right now that there's a noticeable hole in our top 6 RW now that Frolik's aged. Neal rebounding in the top 6 could have fixed that. Like if the Kadri trade went through and moved Backlund down to #3C (even if I didn't like the trade) or trying Lindholm out.
I was referring more to what Neal himself has said to the media. Everything I've heard about the guy seems to indicate that he is a good dude, yes, and I'm sure that in conversations with Treliving, he presents the best version of himself. That said, in every interview where he could express accountability, he typically tosses in an excuse or two as well. And since he was traded, he cranked that to max. In that article you posted there, while talking about wanting to be better, he throws in the fact that he "didn't have time to train" in the summer because of all the success he'd had. That's such an eye-rolling thing to hear as a fan.
Putting together the body of evidence, what appears clear is that Neal mailed it in the prior off-season, complained the entire season about not being given an extended stay on a line he was dragging down, and then had the management do damage control until they finally rid themselves of him.
Since the trade, we've heard that things were extremely tense in the room, and this was a player that the Flames could essentially not afford to bring back into the locker-room. The fact that they were willing to take on a contract that Flames brass obviously realized was bad, and take on a player who is clearly capable of no more than grit and a bottom-six role, lends major credence to that. This trade doesn't happen if conversations were as positive as they were alleging. The Flames absolutely know that they can go out and get a heavy bottom-sixer for cheap. They specifically made the move that got rid of Neal.
The hole at RW has been a thing with this team since Iginla was traded. Our 2015 run had Hudler at 1RW and .... someone... at 2RW above David Jones. I don't really remember who that was, to be honest. Maybe Joe Colborne.
They tried to address it twice through free agency by getting guys past their primes. It simply hasn't worked. Neal rebounding in the top 6 could have fixed that, but unless he's done a complete 180 as a player, it isn't going to happen outside of a lucky night here and there. It is much more likely to be addressed via a big trade (aka Lindholm) or from within (aka Mangiapane). If Mangiapane plays like he did Tuesday night, our top six will be fine. On the other hand, if every team plays the Oilers like the Islanders did Tuesday night, we'll be annoyed even if we're winning too.
