Is this trade fair for both teams? Calvin for Ball/Ertz/GTate

I'm trying to make sure I build a fair trade for both teams because the other owner is my 12 year old nephew.

Team 1 gives Calvin Johnson
Team 2 gives Montee Ball, Zach Ertz, and Golden Tate

Standard scoring, non-keeper league
2QB, 2RB, 3WR, 1TE (no flex)

His Team:
QB: Brady, Cousins, Roethlisberger
RB: Ellington, Ivory, Vereen
WR: Calvin, Patterson, Michael Floyd, Malcom Floyd, DeAndre Hopkins, Reuben Randle
TE: Owen Daniels, Fleener

My Team:
QB: Stafford, Romo, Dalton
RB: McCoy, Ball, LBell, Hill, Taliaferro
WR: Keenan Allen, Colston, Tate, Jennings, Josh Gordon
TE: Julius Thomas, Zach Ertz

Primary question: Is this trade fair for team 1?
