I'll go with the younger guy who seems to get better each year and is still improving. I have no concerns with Fitz and feel it is a safer pick as well.
While Moss is not old for a WR, athletes age differently and I wonder at some point if he will lose that bit of spurt that makes him special. Plus, there is that concern about Brady being 100 percent. I don't think NE would move Cassell if they weren't confident he is, but there is that concern. No Brady, Moss drops way down.
I like them both of course, but edge to Fitz...........
