Agreed. His injuries notwithstanding, the Chiefs limited his usage a little bit and gave significant carries to his backfield mates. There was always another guy or two there who got decent play, although Jamaal did get a lot of touches he was rarely overused, much to his owners chagrin at the time ?. He did obv miss a ton of time with injuries which ironically also limited the beating he took.
Like a dude above said, I've also owned him in a dynasty for years through all the good times and the bad, and am rooting for him to look like vintage Jamaal all year (and contribute a bit to my fantasy team). I also agree though that I'm not expecting very much, even if he does look like the old Jamaal AND stays healthy all year the Broncos are going to seriously limit his action. Or so they should.
