First of all congratulations - recruiting is very stressful and sounds like you have managed this process with maturity. Having numerous visits offered is a great testament to your academics and sport ability.
My daughter was an athletic recruit (ended up at an Ivy) and has many friends that committed during Covid - when officials were off the table. It is a process full of doubt and it is wise that you are thinking through the “what ifs”.
I think @Mwfan1921 advice is 100% accurate. @Zackattack44 you wrote that this school is your top choice and the coach has told you he gets everyone in. I assume you have gone through the pre-read process and he has this confirmation directly from admissions - then in 99% of the cases you are good. You would apply ED (as requested by the coach) and IF it is 100% doable financially for your family and they agree.
Even though my daughter was committed to a school, she still applied to our state flagship, 2 EA schools (all saying she would have a spot on the team and she told them the name of her committed school) and had essays done for 2 other Ivy schools that told her to contact them for RD if something happened with her ED school. No guarantees - but they didn’t shut her out.
She was 100% honest that she had a commitment - but with Covid, teams getting cut, kids taking a gaps - it was very important she had a plan. I couldn’t imagine a worse way for all of us to spend the holiday break having to scramble - so we (and her school counselor and team coach) were adamant that she be ready…just in case!
She still is not happy that we made her do all the essay work - and we are all glad it didn’t have to be used
I do not know of any D3 school that provides a Likely Letter - I imagine a few do - but it is not common. I do know for my daughter’s friends that were looking and committed to D3’s like Williams, Pomona and Tufts - their college counselor (all from independent schools) made a call to admissions just to make sure it was all good. For my daughter - her school gave out 6 likely letters and 5 other team mates also got in for ED with soft support - it is not an exact science.
Again, Congrats !
