My search hasn't been totally exhaustive, but I've hit most of the high scorers, and I believe that when Chris Wondolowski scored his 16th goal this year, he became the first player in league history to score at least 16 three seasons in a row. The only 3x15 I could find was Raul Diaz Arce in the first three seasons of the league. Here's a partial table of total goals scored through three seasons: RDA (1996-1998)-56 Roy Lassiter (1996-1998)-55 Wondolowski (2010-current)-51 Carlos Ruiz (2002-2004)-50 Taylor Twellman (2002-2004)-47 Mamadou Diallo (2000-2002)-47 Juan Pablo Angel (2007-2009)-45 Stern John (1998-1999)-44 (only two seasons played) Twellman (2005-2007)-44 Dwayne De Rosario (2009-2011)-42 Jaime Moreno (1996-1998)-42 So I've been trolling around, and I think he's the first guy to get to his number since the opening years of the league. Also, it's looking like he has a shot to get to 20 for this season. If he did that, he'd be, AFAIK, the only player other than Landon Donovan (2008) to do it while not in his first season in the league (lots of guys have come in, taken the league by storm, and then slowed down to one extent or another). If he got to 21, which is not looking like a bad bet, he'd be the first 'league veteran' ever to get there.
