Jones can spin it however he wants, but we've done nothing to get better. We simply haven't lost the type of players who should make us much worse. If we do a good job in the draft, we do have a chance to be better than we were last year, but so should the teams who have done more in free agency to improve.
He probably sees the offense as being even better with Dak and Zeke in their 2nd year and Dez potentially healthy all season.
On defense:
DT Collins was a starter as a rookie after missing most of training camp with a broken foot. He should be even better.
CB Brown played a significant role as a rookie and should be even better.
Claiborne was out in the 2nd half of the season and not good in the playoffs.
Carr might not have been a starter this year in 2 CB sets if he stayed, with Brown in his 2nd year and Scandrick further removed from his knee injury.
Heath/Frazier replace Church/Wilcox. Is this good or bad?
DLaw won't be suspended for 4 games and might be healthy.
Irving still has room to improve.
DT McClain was good early, but faded late in the season.
Paea/Thorton should be steady veterans at DT.
LB Wilson looked good at SLB. If no Jaylon, he might be the new MLB.
Jaylon has the potential to be great.
Mayowa improved as the season progressed and his knee got healthier.
Tapper has potential that was not available last season.
I see the defense as potentially better, even without the 2017 draft picks.
