Hot starts and cold streaks are meaningless early in the season. A hot start may mean you played 2 or 3 bottom-feeder teams in a row. A cold streak may be related to playing a couple of 90+ win teams in a row. Until you play every team at least one series, nothing can really be determined about the strength of your team.
Example: ronthegenius thought his 140M team was good after sweeping me in the second series of the season. Little did he know that my 140M team is the worst in the tournament, averaging under 3 runs per game. ronthegenius' 140M team is now 10-14.
