What a dumb player for teams to obsess over before a trade deadline
Most trade deadline deals are for players that fans aren't overly interested in. Guys like Savard fetch extra value at the deadline, for all kinds of reasons. But because their value isn't immediately apparent in stats, fans will argue about their worth.
The idea that, say, Toffoli was a significant addition to the Flames wasn't hard to swallow since you can see his goals scored the second you look him up. Energy players, depth forwards, big defensive defensemen, etc, just don't have that same immediate allure to a casual fan.
