Winthrop vs. Coastal Carolina Officials' Error on FT? (Video)

[crosscountry55]

3/8/15: Winthrop vs. Coastal Carolina, 2:30 remaining 2nd half, ESPN2.

CC player goes to the line for a 1-and-1, only the L signals "2". The player misses the first. No one in the lane moves. Then there is a dramatic pause, and finally the C moves in for a discussion, realizing the crew probably messed up. Brief discussion, announcer says, "that was a 1-and-1; it should be Winthrop basketball." Usual ill-informed chatter.

I'm thinking since there was no team control when the error was discovered, the POI should be an AP throw-in. Winthrop had the arrow, but it appeared the officials awarded an ordinary throw-in because the arrow did not change after the throw-in.

Did the crew handle this correctly? Seems like they didn't. One mistake turned into two.
