How does my team rate? my league is 1-qb 2-rb 2-wr 1-TE 1-flex 1-k and 1-Def. Its a 10 man league?

Good, but you could def improve your WRs. Maquoi is going to get double-teamed now and people are going to regret jumping all over Crabtree. It will take him some time to get used to the NFL. I'd pair those guys up and trade them for an upgrade FAST before you see what I mean.
