I don't see Rielly getting the equivalent of 9M from anyone on the market personally.
That will be 8 years 72M. To get that on a 7 year UFA deal he'd be making 10+ on his next deal, and I don't see any team crazy enough to offer that much for him. Rielly is a good 1D, a 15-25 1D, and not an elite one, but still the best d-man on the leafs, and a very valuable player.
If some team is offering him 7 years by 63M all the leafs need to do to beat the offer is give 8 years 64. We give more total cash, and no doubt with the leafs financial muscles he'll get a shit load of signing bonuses + the endorsement opportunities in GTA and an NMC
Leafs should bring him back at 8x8 as I don't see him getting more than 63M at maximum on the market, and more likley it will be closer to 56M (8M UFA salary) so think we could get a 8 year 60M deal (7.5M)
