Snoop will be lucky to make the Chiefs as a #5 or 6 WR, and he'll get little playing time. But, if he's cut, he'll be a good #3 for someone. Dante Hall won't get enough touches to have a breakout year. He's #4 there. Boerigter is their potential breakout guy, and Morton will bounce back, but too much talent there for any one guy to dominate.
Santana Moss will not be any more than a Dante Hall/ Az Hakim type, great returner but not much at WR.
From your list, Lelie will do well, but I expect Curtis Conway to equal or exceed Coles' production with the Jets. Donte Stallwaorth with NO also will be big time.
