Let him believe whatever he wants, he has insider info... a voice inside his head...

As I have posted before...

Glenn Borsi - Season 9 - He wasn't captain, average rating at the end of the season 7.76
Season 10 - He wasn't captain in the first half of the season, named him captain for the second half, after I sold old captain, average rating 7.76
Season 11 - He was captain entire season, average rating 7.76

... so your theory about captaincy slips Stevie G style...
