I'm sure that I heard an announcement at the game that playoff tix were going on sale and that included dates. At most there can only be two games. The first would be either the weekend of 10/31-11/2 or the weekend of 11/7-9. The second match would be the weekend of 11/14-16 but only if the Revs finish 2 or 3 and the 4th seed beats Chicago, otherwise the game that weekend will be in Chicago. I thought I heard in the announcement the dates of the 2nd and 9th (i.e. the Sundays)? Are the Pats at home either of those weekends? Of course, all we know for sure is that there will be a game one of those weekends, but not which weekend yet.
The Pats are home 11/16 (8:30pm) only - so looks like there are no real conflicts. Anyone watch the Pats game last Sunday? What they did to the field was incredible. The section between the hash marks was turned into one long stretch of mud from one endzone to the other. One of the announcers even suggested the Revolution game the night before contributed to the fragile field - LOL! Maybe it's progress that they were even aware that "soccer happens". The grounds crew will have until the 25th (13 days) to get it back in decent shape - pray for sun.
