I would not take Gallop over Fuller or even Stills. There is a reason Dallas lead the league in dropped passes (Gallop was 2nd in the league with 11) and its not their sure handed WRs. Having a great RB does not exactly help the passing numbers, especially when he is not great at catching passes, but it did contribute to Dallas having technically the number 1 rated offense last year.
Also to Amari had 24 more yards but 25 fewer receptions (which is both good and bad because longer yards per catch but less of them), had a lower reception % and 1 more drop but 1 more TD (7 to 8). All in all i would give their year a wash but the problem is that this was one of Hopkin's worst years and its a wash against Cooper's best which if anything highlights the difference between them.
Overall Dallas had a better OLine, but the weapons Houston has just were light years better.
Fuller has yet to play a full season in 4 years(65% game played out of possible regular season games ), yet you would take him over Gallup?
Cobb had a better year than Stills. Same Kenny Stills who has yet to have a year like Gallup, while playing 7 seasons.
Zeke has caught 77 passes in 18 and 54 in 19, yet he doesn't help the passing numbers?
Witten was slow as dirt, but also reliable in terms of placement. Jarwin showed off playmaking when given the chance.
Houston's weapons do no blow the Cowboys weapons out of the water.
Light years? c'mon.
