Raiders mailbag: Mario Edwards Jr. expectations, Derek Carr under center and yes, more Aldon Smith

I’d expect Mario Edwards Jr. to debut in at least a somewhat limited role, maybe in the 15-20 snap range to get his feet wet. It’s impossible to know what Edwards is going to be like after not playing in a regular season game in more than an entire calendar year, but without a doubt, he would be an improvement if he’s near the level he was at last season.
