Face it, that's how most football fans do their analysis. They just look at QB, RB, WR, maybe a TE or two. That's it. Maybe if there's a monster DT or LB, they'll factor that in. But for the most part, they talk skill player, they think skill player, and they predict based on skill players, and skill players alone. And all these Summer time predictions are forgotten by the time training camp starts, to say nothing of the actual season. So it's kind of pointless, other than as idle banter to get you by while there's no actual football.
