Colin Kaepernick hasn't played a single snap in the NFL since January 2017, but he's still a better QB than half the starters in the league ... this, according to the new Madden 22 ratings.

TMZ Sports has confirmed ... the 33-year-old ex-San Francisco 49ers star-turned-social justice icon is featured in the newest edition of the uber-popular EA Sports franchise ... and comes with an eye-popping 81 overall rating.

To compare, that's a higher rating than Los Angeles Chargers star signal-caller Justin Herbert, who just won Offensive Rookie of the Year with 4,336 passing yards, 31 TDs, 10 INTs and 230 rushing yards.

In Kap's best statistical year -- 2014 -- he threw for 3,369 yards, 19 TDs, 10 INTs and 639 rushing yards.

Kap's 81 rating is above Herbert (80), Kirk Cousins (79), Trevor Lawrence 78, Ben Roethlisberger (78), Joe Burrow (77) and Jared Goff (77).
