Did anyone else think that only one person had to ring the bell? I think that's why Tiffany was trying harder. Maria knew she didn't have the strength to get it up there.
They showed only Brian from the married team and one of the Globetrotters ringing the bell. If both teammates had to ring it I think they would have played up Ericka's attempts at ringing the bell since the other two ladies were having such a horrible time.
I say this only two defend the poker players who slowing grew on me, especially Tiffany. I really think they gave it their all (let's face it Maria is just not physically strong) and looked physically exhausted.
