Your rewriterules arn’t correct anymore. You changed
add_rewrite_rule('^video/([^/]*)/([^/]*)/[^/]*)', 'index.php?pagename=video&video_id=$matches[1]&video_src=$matches[2]&video_title=$matches[3]', 'top');
To
add_rewrite_rule('^video/([^/]*)/([^/]*)/[^/]*)', 'video/&video_id=$matches[1]&video_src=$matches[2]&video_title=$matches[3]', 'bottom');
The correct rewriterules for your pages are:
Video
add_rewrite_rule('^video/([^/]*)/([^/]*)/[^/]*)', 'index.php?pagename=video&video_id=$matches[1]&video_src=$matches[2]&video_title=$matches[3]', 'top');
Team
add_rewrite_rule('^videos/team/([^/]*)/([^/]*)', 'index.php?pagename=videos&team_id=$matches[1]&team_slug=$matches[2]', 'top');
League
add_rewrite_rule('^videos/league/([^/]*)/([^/]*)', 'index.php?pagename=videos&league_id=$matches[1]&league_slug=$matches[2]', 'top');
For team and league I assumed your WordPress page is “videos”. If it is the subpage then you have to change “pagename=videos” to “pagename=videos/team” and “pagename=videos/league” in your rewriterules.
