Visby led 82-81 when the ball was recorded to Coleman who from half distance inside the three-second area put the important second and secured the victory to 83-82.
It was the dominant Coleman's 25th point of the evening.
This means that Wetterbygden is ninth in the table with eight points, the same as the eighth Uppsala that has the last playoff spot.
Visby remains on six points as sixth.
The margins could be weighed on a pinch tonight. A´lexus Harrison made a nice "steal" from his own half of the field and rushed through the whole field and put in 82-79 with 1.02 left of the match. The team had the ball but was blown away by the shot clock with 26 seconds left and eventually lost the victory and two points. Harrison was with 27 points best tonight.
