The 6-foot-2.5, 220-pound prospect should be a familiar name to Washington fans.
His father, Peter, was Washington's Linebackers Coach from 2013-14. And Jack's cousin Jacob Sirmon is Washington's other 2018 verbal commit.
Sirmon picked the Huskies over offers from Vanderbilt and Wisconsin, as well as interest from USC, UCLA and Oregon.
We'll have more on Sirmon's commitment to UW shortly.
