I'm a little confused as to what the radical intermediate is for this reaction.

It is ethylbenzene, I just drew the hydrogens in red.. If those are even the hydrogens I should be pushing that is

The way it is drawn, the radical should go on the methyl carbon. But your mechanism is wrong in general. The benzylic site is more reactive and H atom abstraction will occur there rather than at the distal methyl.
