I'm all for upgrades at any position. But realistically I don't see a better option. Draft another QB for sure and have a QB competition next preseason. May the best man win. But I have seen the opposing defenses crashing thru the OL the second the ball is snapped, nobody is going to do very well under those conditions. We have one good WR that has trouble staying healthy, Robert Woods is serviceable and then it drops way off after that.
The defense is harder to decipher, is it players or scheme? Swartz came in and turned it around in one season. I think a new HC slash DC could turn this defense around. My vote is for Wade Philips, he puts players in a scheme to succeed based on their skills.
Just my opinion, we will see what happens,
