onrush What do the orange bar graph type icons mean in ranked game stats?

[THXII39]

Some players have a little orange bar graph looking icon next to them in ranked match results, orange regardless of which team. Usually I only see one or two, but recently a ton of players had one. What does it signify?

Just looking more closely at these images, and I see some players don't have a rank icon but a red or green block with a number. Any idea what these mean?

Another player has what looks like the Onrush 'O'. I'm guessing this player is still in the initial 8 match ranking process to determine their starting rank?

The orange bar graph is network latency issue with that player.

The players with red or green block and a number have not completed placement matches yet. The number is their level and color changes style as you level up higher. 400 is max level.

The OnRush 'O' icon for a player indicates that it's a Bot player.
