The point is DA made some fantastic moves in the past that brought a championship to Boston (should've been 2, had Perk not gone down with Appendicitis). That isn't in question...
What is troublesome is how he has taken such a drastic fall. How can you explain that? In my observations, Danny has appeared to have bloodshot eyes, red cheeks, and occasional slurred speech. I only have one interpretation for that... and while I may be off the mark, or speculating, I am concerned that he drinks to get drunk.
That does not bode well for our future. Unfortunately, history repeats itself (Chris Mullin, Rony Seikaly, Vin "the Hitman" Baker).
