Leicester Riders coach Rob Paternostro says his side have to improve their shooting after a wayward display in the 89-79 home loss against Glasgow Rocks.
Riders remain third in the BBL after the weekend's games despite Saturday's defeat against the fourth-placed Rocks.
Paternostro told BBC Radio Leicester: "We just couldn't buy a basket and that puts pressure on you defensively.
"If you can't put it in the hoop then you will be in trouble. We couldn't hit a shot. It was a difficult night."
Riders started brightly, hitting the first five points of the night. But they missed injured Great Britain skipper Drew Sullivan, who has a back injury, and soon slipped behind.
Bursts of 10-2 and 8-0 saw the visitors take control, and although Riders rallied briefly after half-time, Rocks were able to see out the win.
Paternostro added: "We had opportunities to get back into it but they played well. They are a tough match-up, they caused us problems and defensively they did a really good job.
"All the credit goes to them. When they are clicking they are tough to beat.
"Sometimes we can get a little ahead of ourselves and think we are playing a team below us at home and will be able to win. But every week if you don't play well you will lose."
