We traverse a fascinating litany of top-tier North American professional indoor soccer leagues with pioneering player, record-setting coach and now, current Major Arena Soccer League (MASL) commissioner Keith Tozer.   In a pro career spanning more than 40 years, Tozer has literally done it all in the indoor game:

• Playing on original Major Indoor Soccer League (MISL) sides like the Cincinnati Kids, Hartford Hellions and Pittsburgh Spirit;
• Dually playing/coaching for the American Indoor Soccer Association's (AISA)  Louisville Thunder and Atlanta Attack; and
• Coaching both the last two seasons of the MISL's Los Angeles Lazers and, legendarily, winning six titles in 22 seasons across four leagues with the Milwaukee Wave

Tozer is not only the winningest coach in indoor pro soccer history (amassing over 700 wins), but one of the most successful overall US soccer coaches of all time.    Buckle up for a wild ride across the rocky terrain of professional indoor soccer - including an outdoor detour with the American Soccer League Pennsylvania Stoners, coaching US teams for international futsal tournaments, and whatever happened to Mark Cuban's much-hyped Professional Futsal League.   And, of course, an analysis of the present state of the pro indoor game - and where Tozer hopes the MASL can take it in the years ahead.
