For clarity, last year's 'top four' played 38 out of 64 games between the four of them. So if we actually have a season this year where our top four WRs play lets say 56 out of 64 games, that'll be a major improvement right there. Add in Sammy being healthy for the games he does play, AND Maclin, and things are looking real good.
BUT the above *on paper* comparison ignoring the injuries, does leave concern.
It's all about context, which some arguments here have been lacking.
