Alright I will try again.
In 2015 the Steelers had 48 sacks - good for 3rd in the league and only 4 off the 52 put up by the league leading Denver Broncos. Of those 48 sacks (all the details here -
http://www.pro-football-reference.co...s/pit/2015.htm), Heyward (7), Tuitt (6.5), Dupree (4), and Shazier (3.5) had 21 of them or just a tick under 44% (43.75% to be exact). It was a reasonable assumption that Heyward could repeat his 7, Tuitt would get more as ascending player, same with Dupree, and a healthy Shazier was/is poised for a breakout year as a defender (so more sacks). Now, that is the good. The bad is that the rest of the sacks came from random "other defender" and no one outside of Harrison (with 5 sacks) could be counted on to replicate or surpass their 2015 total. So is there a pass rush problem? Yeah - basically there is no edge threat besides Dupree and the 2 DE's. Bad if Dupree doesn't improve, gets hurt or otherwise stinks (what we have now) but survivable if Dupree can be a consistent down by down threat (Clay Matthews hasn't had a reliable running mate for years and he terrorize opponents). So the pass rush remains an exercise in roster theory rather than a real thing on the field. One can only hope that a healthy Dupree and Shazier can provide a series of jolts to the pass rush over the course of the season.
In 2015 the Steelers also had a pass coverage problem. They finished 5th against the run and 30th against the pass. Three. Zero. (Data from here -
http://www.pro-football-reference.co...tm#all_passing). So what did they do? Well they basically fired 50% of the starting secondary (Blake and Will Allen) and they let Boykin walk for good measure. Turned over 3 key positions in the secondary to new starters (Cockrell, Golson, and Golden). Then due to injury shuffled that deck to include more rookies (Davis and Burns) and they brought in a lottery ticket in Gilbert.
Just in case the pass rush didn't go as planned (see above) they brought in a disruptive penetrating DT to play between Tuitt and Heyward. This in theory adds another sack guy to the roster and should help the pass rush #'s of the DEs to either side of him - who just happened to be 2015's team sack leaders! In addition to that move to bolster the pass rush, they brought in 2 immediate guys to help one of the worst secondaries in the league (Burns and Davis). I mean what more do you want?
If the above was too much to read - it boils down to this. If you are pretty good at one thing and pretty bad at another - many believe the solution is not to double down on the thing you are good at the total expense of the thing you are bad at. No Noah Spence means Artie Burns is a Steeler. By extension, Artie Burns means Sean Davis is a Steeler (likely go with a "true" CB if no Burns). So when I am speaking of patience, I mean that Spence and Burns are judged off of each other and their respective impacts in the NFL. I have seen nothing yet from Spence that makes me want him on the Steelers roster in place of Burns.
Long story short - this is Lacy and Bell. Or Bell and Arthur Brown. Given their non Jarvis Jones track record in the first round, I'm going to give this team the benefit of the doubt.
