"They deserve better," said Welsh, who finished with a team-high 14 points. "We are extremely sorry for our fans. They show up and scream their hearts out. We want them to bear with us."
The Razorbacks (12-5, 0-4 Southeastern Conference) dropped their fourth straight game with the 73-51 loss, being outscored 14-0 by the Tigers in the game's final six minutes, nine seconds.
"Auburn was better," Arkansas freshman Michael Sanchez said. "We fought hard, but Auburn played better."
The 3-point line hurt Arkansas on both ends of the floor for the fourth time in as many games. Auburn hit eight of its first 10 attempts from beyond the arc en route to building a 38-31 halftime lead.
"We didn't do a good job of running Auburn off the three-point line in the first half," Welsh said. "Auburn made a lot of threes in the first half…If we had cut them down on threes, we might have been ahead at the half.
"We have to dictate pace and we didn't. We have to force them to become a driving team and we didn't do that."
The Tigers (12-7, 2-3) cooled off late, but still finished with 10 makes from the outside.
The Razorbacks' struggles continued, hitting just 5-of-24 from downtown – dropping the team's total to just 13-of-85 in SEC play.
"We are getting good shots, easy shots, but we are not knocking them down," Arkansas guard Courtney Fortson said. "We settled for jump shots and we were not hitting them."
The Razorbacks' inadequacy to hit perimeter shots and defend perimeter shots has left the team baffled following wins over Oklahoma and Texas heading into SEC play. Since then it has been nothing but downhill for the Hogs, who have lost four-straight to start conference play for first time since entering the league in 1992.
"We came off the nonconference schedule and we were strong," Fortson said after finishing with 12 points and nine rebounds. "To go 0-4, yeah, that's a shock.
Arkansas could easily make excuses for the loss. The team was without senior Marcus Monk (eligibility concerns) and freshman Brandon Moore (suspension). To make the short bench shorter, Jason Henry sat in the second half when he couldn't go full-speed as he continues to battle back from knee surgery.
Welsh said despite the setbacks, the team has to take responsibility for its performance on the court.
"We have been the walking wounded, but not having a player is not an excuse," Welsh said. "Jason Henry's hurt knee or Monk not being out there is no excuse. We have to find ways to win."
