There are some rare instances of guys taking off in year 3 but from what I witness when a player is going to be something great they typically show signs early on ang throughout i.e ayo donsumu and what Dalen Terry did last night.
I watched pwill last night and saw no difference than what I saw in his rookie year. It's more infuriating since we could have gotten immediate help for him in a trade but we took him out of all trade discussions. Now when akme are finally ready to deal him we are going to get the absolute least value for him since it will likely be next season when he due a deal.
