I also assume it's Melvin Gordon.
I agree that this offer really ages your team a lot, and that is a problem.
Julio Jones is almost 10 years older than either Brown or Moore, and his fantasy numbers will start declining soon. Julio didn't score many more points than Brown or Moore in my 1 point PPR league, so in .5 PPR league, they should have scored about the same amount of points.
1.03 pick is interesting, but with no blue chip draft prospects that stand out at 1.03, I wouldn't get too excited about that pick.
If Brown or Moore (both only 22 years old) would get in a good offensive system with a good young QB, either one of these young WRs could start realizing their true value.
Melvin Gordon will turn 27 this April. and Julio is already over 30 years old, so this offer would come off as a weak offer compared to the up side of either Brown or Moore.
