Nice to hope for but probably not.
Toulouse made clear it’s a long game for them. So see it more that last year allowed them to establish in the Championship, this years target is probably as a minimum top 4, learn and then push next year.
Broncos have to somehow avoid injury to key players, as squad of recognised names are thin. Number of very good kids coming through (at least into a winning structure unlike seasons of yore) but relying on them would at this stage be too much of an ask.
Unless there are a couple of really weak SL teams it’s unlikely, one or either of the two are promoted.
