Idea to show extra game info of friends in game on mouse hover

What if when you hover the name of one of your friends in a game, it shows you the team KDA along with the game time? Then you'd know if the match was close or not and could better decide if it's worth spectating.

It might even be cool if you could see a small representation of the team gold graph like at the ending screen in the overview panel. Games with lots of spikes tend to be more entertaining than ones with a steady trajectory.
