Replying to Lacrosse Players Advice?

hey, so i played on this really good summer team last year with our varsity coach. i played with kids all a year older than me and got a ton better, i was 15, they were all 16

so this year, i tried out for the team again, and made it, but i made the u16 team and not the u17 where all those older kids are playing again.

heres the thing. i like playing with kids older and better than me, i get better. i also know these kids. i also think i am good enough to play with them, or keep up atleast. also, the u17 team has so many amazing players, like 3/4 of the team can get recruited and are for sure...

i didnt have the best tryout because it was kinda over the winter and i hadn't played in a while. now that im back in the season, i have definitely got back into my game and im doing great.

so i really do want to get on the u17 team. how do i ask the coach? hes not the best guy. hes kind of an asshole. he left our school and ditched us, he doesnt answer emails from me or my mom (like business emails from my mom even...). so i would email him, but hes not very like nice about things and what not, and he probably wont even answer.

so how do i ask him? how do i not beg and show him that i really want to be on the team.

any advice would be good
