2025 NCAA Runner-Up Mackenzie Miller Enters Transfer Portal

2025 Division I NCAA Runner-Up Mackenzie Miller of BYU has entered the transfer portal. Miller made history two weeks ago becoming BYU’s first All-American since 1991. She has one year of eligibility remaining as she just finished her junior season.

Miller made huge strides this past season under first year head coach Tamber McAllister. Prior to this season, Miller had never earned an invite to NCAAs. This season, she finished 2nd in the 200 breast in a lifetime best 2:05.03 and was 7th in the 100 breast in a 58.39. Miller notably swam the top time in prelims of the 200 breast with a 2:06.12 to swim out of lane 4.

Time Progression

High School Freshman Sophomore Junior
100 breast 1:01.39 1:01.06 1:00.30 58.14
200 breast 2:13.00 2:11.94 2:10.98 2:05.03
200 IM 2:03.64 2:03.57 2:02.86 1:57.62

Miller’s 29 points at 2025 NCAAs are the most in the 21st century for the school. It also earned the school a 23rd place finish overall. She was the only NCAA qualifier for BYU on either the men’s or women’s side.

She becomes the latest NCAA qualifier to enter the transfer portal as Macky Hodges has already announced her transfer from USC to Indiana while NCAA Champion Bella Sims of Florida entered the portal yesterday. The transfer portal closes on Apirl 25th for women’s swimming and diving.

Entering the transfer portal does not require a student-athlete to transfer rather it allows for the student-athlete to discuss with other coaches about the possibility of transferring. On rare occasions, the student-athlete returns to their original school.

Semantic thing but the BYU swim Instagram account calls her Mackenzie Miller Lung so do we do the same thing now? Is this like Blaire Anderson where we kept calling her Blaire Bachmann until A&M announced her as Blaire Anderson?

Good for Miller.

But this is not a great trend. Almost de-incentivizes non-juggernaut programs to develop their swimmers into national title contenders. Because the faster they get, the more likely a power money program is going to be able to steal them away. The Carle Fierro phenomenon is fun to watch with the blossoming age groupers, not the fully-formed adult athletes simultaneously getting an education.

There are plenty of programs that develop swimmers and have them stay; just because we see these stories of insane growth curves and then a transfer doesn’t mean it is a trend.

That’s why building a great culture is also important. You need to give these swimmers a reason to stay as well. I will say transferring your senior year is an interesting decision though.

“just because we see this thing happening more and more doesn’t mean it’s actually a trend” is not a great argument.

I’m sorry, but since when can you transfer for just your senior year of college (outside of the COVID uncertainties and exceptions)? I thought the same thing when I saw Baylor Nelson enter the portal yesterday. Don’t most universities only accept people transferring in as sophomores or juniors?

Also, with only one year left, why would you want to transfer for your senior year?

BYU is pretty unique. I’m guessing most people choose to go there for reasons not directly related to athletics. Also guessing that some people choose to leave for reasons not directly related to athletics.

It looks like she is married to someone who is not a BYU student. So possible they are relocating together?

BYU culture is unique.

In the portal era, people transfer no matter how many years they have left. You see it all the time in football and basketball. It is what it is.

I don’t have much to add other than “Tamber McAllister” has excellent mouth feel.

Might replace “the human torch was denied a bank loan” as my vocal warmup phrase.

Wow! She will be a big pick up for any team. I guess she has one year left to monetize her swimming, why not check the market and see if anyone has decent NIL money available. She really had a fantastic season with the new coach at BYU.

Of course she is also taking a chance that she finds another coach who will keep her scoring that high. But sure will probably make the NIL $ up front
