Buffalo is better than the Jets. They are younger, faster, building through the draft, etc. They just need leadership, which they lack.
There's no question that Takeo Spikes is a monsterous leader (though I LAUGHED at that Sunday Night Football intro of him calling out Ricky Williams in 2003, to just get owned by Ricky after having a 150+ rush yard game); JP Losman has to step it up and be that leader he was drafted to be.
Jets may turn out better than the Bills this season, if they use their 2 first rounders correctly and their other draft picks correctly as well. They need to get younger. I'm just not sold on Eric Mangini, yet. But I am leaning towards Buffalo having a better season than the Jets.
