MLS takes + code & math. That's the bit
If the Rothrock analysis at Sounder at Heart worked for you, here's how I built it:

Not too bad for someone who spent their entire K-12 education in special education for writing.

Special thanks to @jeremiah.sounderatheart.com for publishing and @mattdoyle.bsky.social for posting so much written content that I could delude myself into thinking I could do it too.
How much is Paul Rothrock actually worth?
A deep dive into the numbers behind the hometown hero's market value.

His stats say paycut. His resume (28, proven) says raise. What did Orlando pay him?

🇵🇾 BREAKING: Orlando City is finalizing a deal to sign Paraguay int'l goalkeeper Carlos Coronel, per sources.

FMV pegs him at ~$285k, but factor in performance on limited minutes? Closer to $315k IMO.

Per sources: Former #Sounders defender Jonathan Bell has signed a contract with #AustinFC After testing the free agency market and talking to several teams, JB will play for Nico Estevez next season. As I had mentioned before, I think Bell is a good addition to that Austin roster.

Think Frei's worth $350K? The model says yes but guaranteed years + escalators are the real levers that make or break the value.

Curious what @lobbingscorchers.com @sounderatheart.com @elrolonw.bsky.social think about Frei's fair market value 👀

With all the debate over Paul Rothrock's contract, I ran a KNN analysis on his '25 statistical peers. TL;DR: Accounting for age and breakout season premiums, his performance-based comp should be ~$515K at current MLS rates (age: +$81K, breakout: +$28K). @lobbingscorchers.com @sounderatheart.com

Anyone else just over the current USMNT? I think the path forward is to be the Kings of CONCACAF. Embrace our soccer heritage

Post '26 world cup I would love for the USMNT to embrace the CONCACAF mentality. Bring back Bully Ball

After the Houston game, I will have a short 2 min hit on who JF compares too in past Sounders line ups both through Stats & Video analysis. 👀
