An oldie but a goodie but have to include it. It sounds great to use those subjective pronouns (I, he, she, etc.); they’re (mis)used because people unfortunately think it makes them sound more intelligent. Of course, when used incorrectly, the opposite effect is achieved: sounding less intelligent than more intelligent (to those of us that care about such ephemera…).
From a rules standpoint, any object of a preposition (between of course being the preposition) requires the objective form: between him and Russel Wilson, however high-fallutin’ it might sound (sound) to use the subjective (he) instead.
