You’ve kind of answered your own question. If there’s doubt in your mind, it’s NOT a safety. Looks like it has around a 50% admit rate. I think you need an admit rate of 60% or 70% to be a safety, as well as having stats at about the 75th percentile.
Oftentimes the state flagship is not a safety for anyone. Western Washington U would be more like it. However, if U Dub offers EA that would be one way to hedge your bets.
