You guys are focusing way too much on who starts and who comes off the bench. Forget that for a moment, assuming Fitz is above Jones in the pecking order and makes the 17 when fit, where do you think he plays when he comes on the field? Almost certainly on the edge because that's where he belongs, and Barnett's versatility means if they're all on the field at the same time it's likely him (not Fitz or Frizell) who moves into the middle. That might only be for part of a match, but it could happen. Arguing that Fitz will not see any first grade, or that when he does it will be as a middle forward because "Barnett is too good" is frankly ridiculous. Barnett is so good he can do both as and when required. Fitz is a mediocre edge backrower, who is better than Jones, and that's where he will play.
