You're not a fan of Debrincat. That's fine.
You're encouraged by Berggren. Again, fine.
But you're taking multiple blips on the radar (ADB's production last season, Berggren's production thus far), ignoring some essential context (linemates and usage, for starters), and making blanket statements that paint a picture of how it's not possible for this to be anything other than a disaster if Detroit trades for him and signs him long term.
That's not a lack of reading comprehension by your audience. It's arguing in bad faith to begin with.
Show me links of players you like better that are also available and interested in Detroit, or that fans could have reason to believe will be in the not too distant future. Show me data that argues him as a bad fit on Detroit's roster, as opposed to, "He's short and didn't score 40 with Ottawa (when on a second line with his intended 2C injured), so he will be underwhelming on the Wings (when on a first line with Larkin and Raymond)." Use more than just emotion to explain what leads you to believe that a team who just signed Compher until he's 33 is at minimum tolerable, if not acceptable, but signing Debrincat until he's 33 would be an albatross (when mountains of money are coming right back off the cap over the next few years, and there are several prospects who will be on ELC deals).
Saying you'd rather have somebody else is one thing. Saying there's no possibility of success is another.
