If Tavares is a bridge to a better team in the future, he's redundant. If he's part of the immediate solution to the mound of problems you've identified, he's a pretty poor one. In either case, I don't see the logic.

Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
