I don't know what your team is but, believe what you want to believe. I think last year was mostly a coaching problem that has been solved. Mac isn't Brady, but he'll be fine. I am absolutely confident that those two guys will help the offense more than any player they could have picked would have. No skill position player in round 4-6 is likely to be more than injury depth with the possible exception of TE.
Every great once in a while somebody gets Amon Ra St. Brown in round 4. Tony Pollard panned out. But after a couple of years, many 4th round guys are out of the league, especially at skill positions. Those were the only two true impact offensive players I could find out to 2017. A few mediocre guys like Will Dissly or Bellinger and Josh Reynolds who is above average. Take a look.

My only real complaint came in round 3, where two TEs, Kraft and Washington, were available. Some thought Washington could move into round 1. But the guys that actually got picked were in a very different order than what the analysts projected for TE.
