"That's an SEC record. Congratulations," Kennedy said, looking at his star senior.
And he kept shooting.
Luckily for the Rebels, seven of those 3s were good, helping Ole Miss rally from a 13-point deficit to beat Mississippi State 78-66 in the second round of the Southeastern Conference tournament on Thursday night.
Henderson and Jarvis Summers each scored 21 points to lead the Rebels.
Henderson constantly circled the perimeter as he sought passes for open 3s. He said it was no coincidence he found more open shots in the second half, when the Bulldogs appeared to grow weary of chasing the guard.
"That's pretty much how it is in a lot of games," Henderson said. "In the beginning of games teams are real anxious to guard me.
"I never stop running."
"Or shooting," Kennedy added quickly with a smile.
Henderson, the MVP of the 2013 tournament, sometimes reacted to his successful long-range shots. He struck animated poses, slapped the scorer's table and slapped the floor.
"There's only one Marshall Henderson," Kennedy said.
Ole Miss (19-13), the defending SEC tournament champion, will play Georgia in the quarterfinals on Friday night.
Kennedy said the Rebels had extra motivation as they need more wins — and probably another SEC tournament title — to make the NCAA tournament field.
Mississippi State scored the first 10 points of the game and kept the lead almost 32 minutes. Ole Miss took its first lead at 57-56 with 8:11 remaining on a layup by Ladarius White.
Following a 59-59 tie, the Rebels pulled away as Henderson and Summers combined for three straight 3-pointers.
Craig Sword and Fred Thomas each had 16 for the Bulldogs (14-19). Thomas spent much of the night chasing Henderson. He said he was slowed in the second half after turning his ankle.
"I really don't get tired," Thomas said. "My ankle was killing me."
Mississippi State ended a 13-game losing streak by beating Vanderbilt 82-68 in the first round on Wednesday night.
"I thought for about 60 minutes in this SEC tournament we showed how good we could be, and how bright our future is," said Mississippi State coach Rick Ray.
The Bulldogs made only 4 of 23 shots from the field (17.4 percent) while being outscored 43-22 in the second half.
"I knew we would come down to earth a tad bit," Ray said. "I didn't think it would be that precipitous of a drop."
It was only the second time the Bulldogs and Rebels played in the SEC tournament, following a 73-64 win over the Rebels in 2003.
Mississippi State played like anything other than a No. 14 seed in the first half against their state rival Rebels. Led by Thomas, who made three of four 3-pointers in the opening 20 minutes, the Bulldogs made six 3s in the half and led 44-35 at halftime.
Henderson, who averages more than four 3-pointers per game and has at least one 3 in an SEC-record 65 straight games, had a slow start. Henderson missed his first 3-point attempt and then was sent crashing to the court when his second attempt was blocked by Sword.
Henderson recovered to make three of 10 3s in the half.
The Bulldogs took their biggest lead at 51-38 early in the second half before the Rebels pulled within five at 51-46 with an 8-0 run capped by Henderson's 3-pointer.
After White's basket gave Ole Miss its first lead, there were two ties before the Rebels pulled ahead on a three-point play by Aaron Jones and a 3-pointer by Summers for a 65-60 lead.
Henderson then launched one of his trademark turnaround 3-pointers, stretching the lead to eight points. He launched yet another successful 3-pointer for a 71-60 lead.
Georgia's Jody Patton had the old SEC tournament record of 17 3-point attempts against Tennessee in 1991.
And he kept shooting.
