I feel like TJ is overkill for the 3C spot. He can range anywhere from a 70 point top line center to a 50 point great 2nd line center in any given year, but you know he'll get damn close to a PPG in the playoffs. I think that's just as overkill as trading for Duchene to make him the 3C. I wouldn't mind getting a top-6 center to be the 3C, but I'd be looking at average to lower end 2nd liners if I wanted a top-6 center in the 3C spot. Someone exactly like Staal for example. I wouldn't be looking at legit 1st liners in that spot.
If we're talking about someone like that, I'm going after guys like Staal, Henrique, RNH, Zajac or Little.
