In your league, you definitely want to grab Edge over Lewis in your league. Simply put, Lewis doesn't factor into the passing game in Bal. as much as Edge does in Indy.
In generalities, I'm presented with the same conundrum in my upcoming draft. The Lewis trial scares the crap out of me. I do think if he plays he'll put up 1500 yards rushing, another 200-300 receiving and about 8-10 TDs, but I see Edge being able to put up 1400 yards rushing, 400 receiving and 8-10 TDs as well without legal issues. Throw in the fact that Moss more than likely will be on the board and that's a big pickle. I'm leaning towards Edge.
I like simple pleasures, like butter in my ass, lollipops in my mouth. That's just me.
