An important part of whether we're better "on paper," as you put it, is that we have FIVE starters coming off serious injury who were 100% healthy this time last year. Two of them tore ACLs in the last month of the season, so we'll have to suffer through the first part of the season without them.
We're better at safety and DE, but it's hard to see how much of anywhere else, and we're worse many places.
-LT: I'm far more worried about Clady than this time last year; he played on a bad knee throughout most of 2011, then missed most of last year with a lis-franc injury to that foot.
+LG: Here's hoping Franklin transitions well; I concede he probably can't be much worse than Beadles.
+C: Ramirez will start unless someone outplays him, and he's better than Walton (Koppen was better than both, but this time last year we hadn't un-retired him due to Waltons injury.) +
0RG: Vasquez should still be solid, but he was last year, too.
-RT: Clark? Schofield? The latters scouting report says he struggles with quick edge rushers as much as Clark and Franklin do (which is a lot,) and neither have Franklins push.
-QB: A year older, and unlikely to shatter all the records he set last year.
-RB: Starter's gone; hopefully Ball can passblock now—and so can his backup (whoever that is....)
-WR: #2 is gone; I doubt a second round rookie's ready to fill his shoes, and if Caldwell could he'd have done it last year.
-DT: This time in 2013 our best DT wasn't coming off a dislocated hip (at 330+ lbs.!)
-DE: This time last year was pre-Faxgate; Ware's a stud, but is he better than Doom+Ayers? Doubtful, and even if a healthy Quanterus Smith is more hit than hype it's still a net loss.
0MLB: Still as crappy as the whole past decade; I guess once you hit rock bottom and stay there it CAN'T get worse. Yea...?
-OLB: Our former DRoY Pro Bowler's no longer suspended 6 games—he's on IR with an ACL torn just before Christmas. Woodyard's in TN: Anyone know EITHER of our starters? HUGE downgrade.
-CB: Let's be simple/generous and say DRC→Talib's a wash; (even a 1st round) rookie for (even an aging) Champ isn't, and Harris tore his ACL nearly a month after Miller. MASSIVE downgrade.
0SS: Presumably Nacho, so no change.
+FS: Presumably Ward, who I expect will be better than Moore was even before compartment syndrome got him.
Before anyone leaps to mention mid-round picks/Economy Class FAs: Nearly HALF last years starters are gone/severely injured; the bargain bin and midround rookies can't replace SB starters.
So we've improved in 3 areas, stayed put in 3 and worsened in 9. That's only a quantitative rather than qualitative assessment, and YMMV, but I doubt many objectives ones will vary a lot.
"You may be right; I may be crazy but" I'd bet money the only people saying we're better than we were this time last year are the ones who say that EVERY year.
