Evans is a very good checking Center, that's be proven for the past couple of years.
You say he'll take the spot of a young Center, so who currently in our pool of players is going to take his ideal spot, which is #4C? Beck looks to be #3C. Hage is too offensively gifted to be put into that role and he's still 2 years away at minimum. I'm just curious who you have in mind.
If Jake goes to management and asks for the moon, you move him. If he's not being super greedy, I think he's someone who could be kept around.
