Not sure that he is a better prospect, but who knows. Faksa has turned out exactly as the scouting report indicated, and JD pretty much the same. Solid 3rd line centers with some potential to move up to the second line. Seems like that is about the same scouting report on Dellandrea - Hard working, good skater, some offensive instincts but not top end like Robertson. Maybe my memory is off.
I can understand your reluctance to trade him (or any prospect) and think Nill shares it. As I said in a post a few weeks ago, however, this year feels even more right than last year to really go "all in." There is some statistical evidence that balancing now and the future yields balanced, but non winning it all results. Taking chances usually results in a better performance now, with less results in the future. It's worth it if you win. It's not if you don't and there are no guarantees, so maybe the odds are against you and you just hope to be playing the best hockey playoff time. I can see regretting a rental in a few years. Heck, given we didn't win last year, we kind of regret Zuch, all while acknowledging he was just what the doctor ordered.
On the other hand, if he decides to make a trade, it's best to trade from a position of strength, and checking line centers with two way play is something they have a lot of in the system. IF he decides to trade, I think that is what we have to brace ourselves for, rather than delude ourselves into thinking we can get someone good for a low pick, Honka, whatever. Give quality to get and all that.
