i havent seen bb2 but dan is pretty good, but i think the cast are idiots. like jenn, why wouldnt she tell shane that dan wanted him out or now ian should tell dani that him and dan have a f2, so dani can be like me and dan do too :O
I think if Dan wins or achieves a close jury vote he is a greater player. However, otherwise I think its fairly even.
Dan's BB10 win was more difficult than Will's BB2. However, Will's BB7 game was probably as good in a higher difficulty setting than Dan's BB14. If Dan wins I'll promote him to #1. If not I will likely consider them the co-best ever.
I will note one more thing though. Will could return a third time and still play the game well. I do not believe Dan could ever play the game well again after this season.
