Snape + Quiddich?
Okay, so recently I made post about your part in Quidditch squad, but what position would Severus have? (If he liked Quiddich and would want to be on the team ofc)
Some time ago I found cosplay of Snape in Quiddich outfit - it looked so good!
Honestly, I can't see him playing Quidditch. He's one of the nerdy kids, not a jock… even from a very young age (11) he makes it clear that he values "brains over brawn".
If Snape liked Quidditch and wants to play it, I guess he'd end up becoming a Seeker.
Oliver Wood talked about build while explaining Seeker to Harry and Snape seems similar to Harry in built so he'd be most suitable as a seeker for the team.
I agree with Heatherlly there. He stated himself that he is the kind of person who values brains and I see him show more interest in something like chess than Quidditch. He probably would go to games to show support for his friends and as a matter of house pride.
If he actually did play, I agree with Naaga that it would be as seeker. It is a less violent position than the others and needs focus and the ability to trick your opponent
