WASH/UCONN: Why not foul at end of regulation?

[TGR]

Why wouldn't WASH just foul a UCONN player near the end of regulation rather than allow a three point tying shot to be taken? Had WASH fouled the dribbler coming up the court, he would have gone to the line to shoot two free throws. The only way that WASH would have then gone to overtime is for the player to make the first free throw, purposely miss the second, be fortunate enough for a teammate to get the rebound, and then fortunate enough to have that teammate make a last second desperation shot. All of this to just tie the score. However, they allow one of UCONN's best shooters to get off a three pointer. Can someone please give me a valid reason for allowing the latter? Thanks for any insight into the reason for not fouling.
