Overall I like this squad.
Personally, I do not think that I would have gone for a second TE as early as you did, though. If it was Gronkowski that would be a completely different case but grabbing Davis in the 6th doesn't make the most sense to me. Yes, you can
play him in your flex spot but at that same draft spot you could've grabbed a running back in the tier of Eddie Lacy, Shane Vereen, Gio Bernard etc. I think I would like your team a bit more with a RB in that slot than a TE because the TE limits your flexibility. You have to start Davis in the FLEX slot because Graham will always be a better play than him unless there is a bye or an injury.
Now this isn't to say it hurts your teams overall quality. You landed Davis at a reasonable value, about where he should be going in this type of league. I love your opening 4 picks, and your WR depth. You are a little light at RB, considering that your RB3 and RB4 are both backups - albeit the two best backups in fantasy. Due to injuries at the RB position I usually like to stockpile backs to give myself options which passing on Davis would have allowed you to do, but healthy years from Spiller and Bush or injuries to Foster and Pierce puts you right back at the top half of the league.
Good luck and welcome the Cafe
