I don't know if this has been noticed, but last night TheRiot stole his 6th base with only one caught stealing. Six steals in less than 50 plate appearances. Extrapolated out to the 550+ PA of Pierre, that's 66 steals and only 11 caught stealing . And that's a very good number indeed. In contrast, Bynum has 7 steals and 4 caught stealing in about 100 AB (that that ratio of steals to caught stealing means that he would have been better off not trying).
So, if speed is an important part of being a lead off hitter, and if TheRiot is, in fact, an extraordinary base thief, wouldn't he be a logical full time second baseman next year and lead off hitter? It would solve a number of problems and allow the Cubs to explore other options in CF.
