Grant Williams and the Boston Celtics were desperately trying to hold off the hard-charging Cleveland Cavaliers on Monday night. The Cavs overcame a 14-point deficit in the fourth quarter but were still 0.8 seconds on the brink of a painful loss.Williams was fouled and was sent to the free throw line to possibly win the game for the Celtics. Cavaliers All-Star guard Donovan Mitchell tried to get into Williams’ head with trash talk. Boston’s power forward proudly and confidently declared that he’d make both freebies, which he ended up missing.Basketball fans promptly and viciously trolled Williams for his misses:“Bro thought he was Larry Bird”Jacob 🏀⭕@SexIandCAVS@ClutchPointsApp @CavsNationCP Bro thought he was Larry Bird 3154@ClutchPointsApp @CavsNationCP Bro thought he was Larry Bird 💀💀One even suggested that the soon-to-be restricted free agent Williams could end up playing somewhere else next season:“He almost tricked me into thinking he was a pure hooper, then he had to go and reveal what he really is.

He would even tell them where he would put himself in position to shoot and the shot he would take. It is a trait only the best of the best have tried copying.Grant Williams' confidence will be something coaches and players will appreciate. However, failing to make even one free-throw to possibly win the game will be something that might never be removed from Williams' career.The Cleveland Cavaliers also did their part in trying to put pressure on Williams. After missing the first one, coach J.B. Bickerstaff made a few changes to his lineup on the floor. The move "iced" the free throw shooter for at least 45 seconds, just enough to allow the pressure to pile on.Rob Perez@WorldWideWobThe Cavs masterfully ice Grant Williams at the line, causing a near 45 second delay between the potential game-winning free throws. youtube.com/live/N_wcQznkW…4504321The Cavs masterfully ice Grant Williams at the line, causing a near 45 second delay between the potential game-winning free throws. youtube.com/live/N_wcQznkW… https://t.co/47vCxixZUJAnd just as the Cavaliers hoped, he muffed the second shot, sending the game into an extra period.It was all they needed as the Cleveland Cavaliers outscored Grant Williams' Boston Celtics 9-5 for a hard-fought win.The Cleveland Cavaliers could have won the game without desperately needing Grant Williams' missesThe Boston Celtics didn't have NBA All-Star game MVP Jayson Tatum, Al Horford and Robert Williams against the Cleveland Cavaliers. They also played the second night of a back-to-back set. Boston arrived late after a marathon two-overtime loss to the New York Knicks on Sunday.The stage was set for the Cavaliers to run away with a victory on their home floor against a tired Celtics team. Instead, Boston's resiliency showed, keeping Cleveland at bay for nearly the entire game.Grant Williams, who usually starts when Jayson Tatum is unavailable, came off the bench for Blake Griffin. Williams played 16 minutes and finished with 12 points and four rebounds. He also hit four of his five 3-point attempts.The undersized Williams impressively battled the twin-tower combo of Evan Mobley and Jarrett Allen. He was both competitive and crucial in the Boston Celtics' attempt to break their two-game losing slump.Bleacher Report@BleacherReport"I'm gonna make both"Grant Williams before missing game-winning FTs 7885632"I'm gonna make both"Grant Williams before missing game-winning FTs 😳 https://t.co/1naXwJOBL9Grant Williams, however, failed to deliver when the Celtics desperately wanted him to. Those missed free throws could hurt him and the team for the rest of the season, particularly if they fall down the standings.You may also like to read: Report: Grant Williams is unlikely to receive contract extension from Boston Celtics
