Colon reminds me of a car I once owned. It had several major issues, seemingly unrelated...No sooner would I get one issue fixed than another one would pop up. Every time, someone would say, "If you just fix this problem, you'll have yourself a good vehicle." After about 4 big $$$ repairs, I finally had to conclude the thing was a money pit, a lemon that would continue to keep sucking away my money and give me back not enough in the way of return. I decided it would be better to cut my losses and move on.
I suspect the Steelers have reached the same point with the Colon.
