Elias Sports Bureau notes this morning that Tavares needed fewer games to get to 20 goals than any Islander since Ziggy Palffy did it in 1996-97 in the Isles' 29th game. (Palffy scored 48 goals in 80 games that season)
Elias also noted that Tavares reached 20 goals in 70 games in his rookie season, and now 52, 48 and 33 games in the seasons since.
If he keeps up this trend he should reach 20 goals next season by Thanksgiving. :)
