Ollie Robinson turned on England form at Hove.
But he was delighted with the team effort as Sussex took command against Leicestershire.
Robinson took 3-36 to have the visitors in early trouble in their Championship tussle.
Sean Hunt took the four final wickets to bowl out the visitors for 275 before Sussex closed their second innings on 66-2, a lead of 233.
Robinson said: “I thought we have been exceptional from the get-go.
“To get 442 on that pitch was a great effort and John Simpson played unbelievably well and then us bowlers have just toiled away.
“It was nice to get three wickets and not have to come back again at the end.
“It showed we’re bowling well as a team.
“Throughout the season so far it’s not been the same person standing up when we needed a performance.
“It shows the depth that we’ve got which is making us into a really good team.”
Sussex are chasing a third successive home win in the Championship.
Robinson said: “We feel like this pitch isn’t going to get better. It’s starting to spin so hopefully we can bat for maybe three-quarters of the day tomorrow and push on and hopefully win another game.”
