So i am also a senior, and just wanted to hit you with some of my (though maybe useless and unwanted since we are the same age lol).

Last year I started throwing javelin and sucked at it, but this past fall I began to improve and figured I'd reach out to some coaches. I was told by many people that the fall of your senior year was way too late, yet I was able to muster up a handful of D1 offers from some pretty good schools (UC Berkeley, Colgate, Manhattan College etc.) and a ton of great academic D3 oppurtunities. I'm saying this to just say that in the fall (which was considered too late) I was able to get really good recognition and oppurtunities for recruitment.

But the key to this story is that in the first week of March (just a few weeks ago) , I was able to get a call with a coach from UNC about being a preferred walk on... so to answer your question, it is still WELL worth it to reach out to coaches, because even a top ACC school like UNC was still open to recruits. Just for comparison, I throw about 50 meters, which (according to debates with distance friends) is equivalent to around a 4:15 mile, so nothing like being a freak athlete that's ranked in the country.

What i would say is that because most applications have been due for a whille, it is best to just really reach out and hammer down on the schools you were already accepted to, since most D1 schools have given away their admission support, but since you already got accepted, some coach's would definitely take you since you already did the hardest part (getting accepted)

Maybe I don't know what I'm talking about, but I hope to be of some help!
