Botman and Burn both play on the left hand side of a centre back pair. Botman is expected to be better than Dan Burn (I know, I know, he's signing for us so he has to be overrated and shite and all that incredibly balanced stuff). With those two things in mind, it makes sense to have Botman ahead of Burn, but that doesn't mean Burn won't play an important role this season. Hell, they might play one of them on the right, who knows? But this is one person's opinion about who should be playing.
For what it's worth, that 'Team that tries' banner was in response to our previous owner's obvious absence of ambition and the many lackluster performances in 2014/15 that almost lead to another relegation. I think it's first outing was the game at Leicester where we got pumped 3-0 and ended the game with 9 men.
