If you had a better RB1/2 I would like this team a whole lot more. Or a better WR2. I think Mccoy and Blount are good RB's, but Blount should be drafted more as a flex than an RB2 until he can prove he is capable of RB2 points. If you had a DMC, Hillis, Gore, Turner or something like that to add to this mix, it would have made your team a ton better. I think if Blount really does well, you will be ok. I'd have Jackson as flex, though.
If that had happened though, your WR2 would be much less concerning. So now you are stuck hoping Dez of JJ do something great. Not a bad team, but room for improvement for sure.
