No one can answer that question seriously without knowing what the other rosters in that league look like and the rules (starting 2 QBs or 3, starting 2 Ks or just one, playing two Ds at once or just one, etc, etc)
One thing I can tell you is you probably lost value by drafting Gronk in the 1st, especially if you are playing only 1 TE. Pretty decent depth at TE this year; would have gotten better value for that pick with an elite WR or RB, imo.
Also, not a particular fan of the players you went for in the later rounds (after D. Jackson), except maybe Dalton, who'd be pretty good value in double-digit rounds and maybe, just maybe Crabtree.
There is simply very little upside to all the other players, imo.
