To get everyone prepared for training camp, which begins in the next month or so, ESPN is and has been doing a series of previews. Right now they are ranking the different offensive and defensive units in the "Ultimate Depth Chart." So far Detroit hasn't been doing too hot in the rankings. It's not really surprising because Detroit shouldn't be ranked too high in any category. But every single time it's the low 20's (27, 28, etc).
Tune in to any edition of Sportscenter for the segment. If you want to be apart of the voting then head over to ESPN's Sportsnation and voice your opinion.
