Even though he sits behind Toronto's attack, for the most part, Bradley has proven to be one of the most valuable shot creators in MLS in the first three weeks, accounting for a remarkable 48% of Toronto FC's shots. (SH/90=Shots per 90 KP/90=Key Passes per 90)
Although Toronto has really struggled with possession in their first three games (they pass a league low 1.5 times per possession), Bradley has been the focal point of almost every sustained spell of possession. His indispensability is best exemplified by his outrageously high (best in MLS) pass usage rate, which is simply the number of passes a player attempts divided by their team's total. Bradley's rate of 23.5% implies that he is either passing or receiving a pass on an absurd ~47% of Toronto FC passes.
He may not always play like the best player in the world, and his ridiculous early season form might digress, but it is self-evident that Michael Bradley is making a strong case as the best midfielder in MLS and, perhaps, its best player.
