Is this the first mention of such a possibility?
"One thing is for sure: The camaraderie between Turner, Norwood and Snelling is unique and each one wants the best for the others. Turner even admitted that he wouldn't be opposed to running in a three-back system. 'If you want to use me, Snelling and Norwood,' he said, 'I'm not against it at all.'"
Of course, it doesn't mean anything at all at this point, but we know Turner's workload was to be reduced for the upcoming season, and a three-back system would be a way to accomplish this.
(And even if it's just mere throwing caps over the windmills, the team spirit expressed here is very well good to hear.)
