I think Bunty is an energy sapper early on with his hard running, and Barnett is more likely to be able to take advantage of any fatigue off the bench with offloads etc. I really like having a captain on the field at all times if possible too.I have mixed feelings about that. Do you try and start strongly and 'weather the storm' while the starters are off or do something like you say? Interesting conundrum for Webby.
