Perhaps you will prove to be right about Burnett not being a leader. However, the idea that Burnett only played well when he was next to Collins is a myth. Due to injuries, Burnett and Collins only played together for 4 games in 2010 and 2 games in 2011. When Burnett had his best season in 2012, Collins was no longer playing.
Ring the bells that still can ring
Forget your perfect offering
There is a crack, a crack in everything
That's how the light gets in - Leonard Cohen
