With MLS on firm footing in Year 20, attendance figures no longer need to be dissected as closely as in the past. There are going to be up weeks and down weeks, but over the course of an eight-month regular season, the numbers will hold steady. MLS has averaged more than 17,800 for four consecutive seasons, with an all-time high of 19,151 last year. The buzz surrounding two expansion clubs will provide a lift, while the death of Chivas USA (7,063) and San Jose’s departure from Buck Shaw Stadium (10,525) will rid the league of two low numbers.

Week 1 announced attendance

1. Orlando 62,510

2. Seattle 39,782

3. Los Angeles 27,000

4. Houston 22,351

5. Portland 21,144

6. Vancouver 21,000

7. Kansas City 19,784

8. Philadelphia 18,022

9. Dallas 15,236

10. D.C. 11,549

Average: 25,838.

The top seven were sellouts.

A late-week snowstorm stunted United’s ticket-selling build-up, but the game-day weather was just fine. And considering how well the club performed last year, the long-term advance sale was disappointing. The crowd count was, by far, the lowest in history for a United regular season home opener. The previous low was last year (13,840), but that followed the worst season in MLS history. United has not drawn 20,000 for a home opener since 2010. It eclipsed 20,000 in 10 of the first 15 seasons.

Week 2 home openers: Chicago, Columbus, Real Salt Lake, New York City FC.

Week 3 home openers: New England, Colorado, New York Red Bulls, San Jose.

Week 4 home opener: Montreal.

Toronto will plays its first seven matches away while BMO Field undergoes expansion.
