Fowler's value on hfboards is very drastically different from his actual value in real life. This is because the fans and media single-handedly INVENTED the idea that Fowler was expendable, Fowler absolutely needed to be traded, Fowler would waste an expansion protection, Fowler can't be re-signed, Fowler isn't a top pairing D and can be replaced by their prospects, BM has no bargaining power and MUST trade Fowler for Tatar or Spooner etc. etc. Not 1 of the things I just said are actually true, but they've been perceived as true by fans and media for the last few months. Thus, they believe Fowler's value is super low.
The shocking part is that some people STILL believe it... after the GM clearly showed no intention of shopping Fowler, and after Fowler showed up in a huge way to start the season.
None of these notions are true, and they never were true. The GM never considered trading Fowler at any point in time, guaranteed. But the fans here already bought his plane tickets.
