Yes, as long as you're not stepping on the tape when you catch the disc.
1 - Does that mean that if I am running up the line, drag the tape (on the side of my sand-socks without noticing), catch the disc with the tape dragged so that it is now clearly not in a straight line with the field corners (OB but inside the tape), I am in?
2 – If I am standing still with one of my feet under the line and thrown a disc, am I in? The argument that the toes were “beyond the tape” in the out of bounds area is going to be a serious issue. Especially because often they are under the sand and not visible.
Please see my reply to Lorne Beckman's comment here for a full explanation:
4 – In all cases or in any case that the foot is below the line tape, how do you know that the foot has not gone beyond the tape?
I'm not entirely clear on the situation you're describing - can you be more specific?
3 – a layout in the endzone where the foot drags the line (obviously unintentional) – is it in?
