Key 0.5 PPR Tarde

I offered A. Thielen for T. Brady+Pats D. Am I giving too much? My team right now is:

QB: J. Goff
RB: C. McCaffrey, D. Henry, T. Coleman, L. McCoy.
WR: K. Allen, T.Y. Hilton, A. Thielen, J. Brown, T. McLaurin, A. Robinson, J. Gordon.
TE: M. Andrews
D: 49ers

His team is:
QB: T. Brady, A. Rodgers.
RB: D. Cook, L. Fournette, C. Hyde, J. White, D. Guice.
WR: D. Hopkins, B. Cooks, J. Landry, M. Valdes-Scantling, D. Westbrook.
TE: A. Hooper.
D: Patriots

What do you think I should do to get the maximum benefit?

I think you could sell Thielen for a better price.
