Here is the break down- gore is off to a slow start and is playing a very tough ravens defense that has a solid defensive line and a solid secondary. But portis will be playing with a hampered knee against detroit which he has a chance to rack up points all beit his knee holds up. I'd say put portis in. He is way too talented and players play injured all the time and still play well. Plus portis was running full speed during todays practice.
