Is it bad to take a RB and WR on the same team with first two picks?

Fantasy beginner here. Got first overall pick in my works fantasy football money league. It's my first time playing fantasy football so i've been doing a lot of research and mocks to prepare. 12 man PPR non-keeper league. Obviously taking Ja'marr Chase first overall and in more than a few mock drafts I end up taking Chase Brown with my 2nd or 3rd round picks and im just wondering if its bad to have my 1st and 2nd round picks be on the same team, even though they're different positions?
