John Harbaugh's Emotional Speech at Tray Walker's Funeral

If you have a couple minutes ... you should really watch this.

Baltimore Ravens head coach John Harbaugh spoke at Tray Walker's funeral this weekend -- remembering his former player as a tough, sweet talented guy who didn't back down from anyone ... including future Hall of Famer WR Steve Smith.

It's clear Walker -- a defensive back -- made quite an impression on Harbaugh and several Ravens players (several attended the funeral including Steve Smith) ... before passing away in a motorcycle crash earlier this month.

Tray's family wanted the funeral to be more of a "celebration of life" -- and Harbaugh did a pretty great job painting a picture of a man who loved football and his family.

We know how much Walker loved the Ravens -- as we previously reported, his family bought a custom Ravens-themed casket for the 23-year-old.
