Agree with pretty much everything. Byrd and Mario are different, I'll go with that but guys like that are essential to winning cause they have the most talent/ability.
I hope Dareus rebounds this season cause ideally, he's the guy to be the vocal and "lead by example" player on the defense. As for Gilmore, I sense he fits more into the former camp with Byrd.
On offense, there's more than enough IMO. All the guys you listed, plus I'd even add Spiller in there too. Guys feed off his energy it seems, because in a league of damn impressive athletes he evokes the "holy sh@t did you just see that" on a regular basis.
