The situation

Ok so this morning I wrecked. I was tired and running late for work and my focus wasnt what it should be and bumped off a curb only I happened to choose where a gutter was due to lack of attention. Grabbed the front wheel and tossed the bike up and me over the handlebars bike falling over in the process.Afterwards it was riding like the brakes were dragging. Rode it that way to work because I didn't have time to mess with it. So I get out of work, go to adjust the brakes before I rode home got them straight (they were dragging) and went to spin the front wheel and it acted the same way. I loosened the nuts on the for that hold the wheel and boom it was spinning freely again. The wheel doesn't look bent or anything that hit might have made it out of true but it doesn't visually look bent or anything of the sorts. Could that hit have somehow tightened the bolts enough to cause it to bind or what do y'all think would be the cause of it. It rides fine now but I'm curious

Tl;dr version
Wrecked. Front wheel felt like it was binding. Loosened the nuts that hold it to the fork and its solved. What would cause that
