Been offered Foreman and Kupp for Landry, Standard League Keeper

Trying to determine if this is a good trade? I might lose out in the short term, but if Foreman and Kupp breakout later in the season and next year I’m in good shape. I currently have WRs - Tyreek Hill, L Fitzgerald, Devante Parker, Pierre Garçon, Rishard Matthews. I’m stacked w Receivers. I’m weak in RB with only L McCoy, J stewart, Buck Allen, and B Oliver. It’s a bet on the future with some possible upside. I’m not losing much in receivers since I have so many high target ones. Any thoughts?
