Tee vs a NEW D

[Whacked]

I think most here would agree that:
1. Our O is anywhere from an 8 to a 10 (let's call it a "9")
2. Our D is anywhere from a 1 to a 3 (let's call it a "2")

For next season, would you rather:
A. Spend loot to keep Tee....and maintain this "9"...but not be able to rebuild this trash D
(Pray some inexpensive pieces can be found to shore up the D a hair)
-OR-
B. Lose Tee, probably slip to a 6-7
(It's not just about Tee's abilities but he commands attn and makes Chase better too)
AND
Spend loot to have a D that is mid-tier ...let's go w a 5-6
