Academy Assistant Manager Meechan admitted results on the night against Bath Rugby, Gloucester Rugby and Exeter Chiefs had been a disappointment to the squad.
But he insisted the young players in the Worcester team will have taken a huge leap forward from playing in that environment.
"It was good for the young lads to get that senior experience and they will be better for it," he said.
"Joe (Nellany) didn't even know he was going to be playing until Monday. He is 18-years-old, fresh out of Warwick School, he has been in the senior programme this week and at the end of the week he is on television.
"In a lot of cases a player will become a star overnight, or sometimes like tonight, when he didn't get much ball in attack, he has to defend all night. His time will come and the big, big thing is he has been able to come here, put a Worcester shirt on and perform.
"I was pleased with Tom (Carlisle) and Ben (Howard) too. We were slightly light with using back rows in the front row so had to use Ben in the set piece. That plays against his type of game, he needs to be in space with the ball. He was fighting up front but did well.
"We are ultimately disappointed by the results," he added. "Jake (Abbott) is a good captain who led by example, but ultimately we didn't come out with the right results. We were very close at times, but we need to be better.
"Sevens puts your basic skills under the microscope and, as a side, we let ourselves down in that respect.
"One of our non-negotiables is physicality and we got hurt at the breakdown at times, there were some unforgivable things and the lads know that, they don't need to be told.
"But we now have to move forward and put sevens to one side, we won't play it again until next year. As a Skills Coach my job now is to look at the factors and put them into a training programme to make sure we get better."
