Terence Crawford says he was gauging Kell Brook's distance at the start of the fight, which made the first three rounds close on the score cards. Once Crawford sized Brook up he was able to win by technical knockout in the fourth round. Crawford's promoter Bob Arum says Errol Spence Jr. will avoid fighting Crawford as long as he can because he knows he can't beat him. Crawford finishes by saying he hopes to revisit a fight with Manny Pacquiao in 2021. ✔️Subscribe to ESPN+ http://espnplus.com/youtube ✔️ Get the ESPN App: http://www.espn.com/espn/apps/espn ✔️Subscribe to ESPN on YouTube: http://es.pn/SUBSCRIBEtoYOUTUBE ✔️ Subscribe to NBA on ESPN on YouTube: http://bit.ly/SUBSCRIBEtoNBAonESPN ✔️ Watch ESPN on YouTube TV: http://es.pn/YouTubeTV ESPN on Social Media: ► Follow on Twitter: http://www.twitter.com/espn ► Like on Facebook: http://www.facebook.com/espn ► Follow on Instagram: http://www.instagram.com/espn Visit ESPN on YouTube to get up-to-the-minute sports news coverage, scores, highlights and commentary for NFL, NHL, MLB, NBA, College Football, NCAA Basketball, soccer and more.
