Major change for Vegas O-line?

According to Raiders beat writer Tashan Reed, the Raiders will hold “active competitions” for 4 starting O-line spots. That includes LG, C, RG and RT, with only Kolton Miller locked in at LT. This unit will be under the tutelage of OL coach Carmen Bricillo, formerly with HC Josh McDaniels in New England. The potentially high turnover here is worth monitoring for Derek Carr and the Vegas offense.
