Fortin is no different than draftees I've seen go for 3.5m. He'd be a candidate to be overvalued by particular teams (mostly Chinese?) who put tremendous stock in the 'elastic effect' due to his 7 OD/PAS/JR and total skill count. It's no guarantee he'd go for much more than 2m, though.
Breton is very nice as well, but would require a more hands-on fine tuning in future seasons. He's not nearly as sexy to purchase. 900k-1.4m+ maybe. Dunno.
It's probably advisable to pony up and get a level 5 (superior) trainer with an affordable weekly salary if you don't already have one. Expensive but worth it for these guys, especially if you decide to train Fortin.
