Not directed at me - but I'm good with any strategy that addresses their top 5 to 6 needs. I don't think you can get locked into one particular mindset e.g. offense in the draft defense in FA since both are highly dependant on what other teams do.
They need;
at least two corners (one at least a serviceable CB1 - I don't care about a lockdown CB, it can't get much worse than last year - just two guys that fit the scheme, are willing tacklers and can give the pass rush another half a second and you would see the sacks increase)
Pass rush - yeah great to have Watt back but he isn't the old Watt, dude needs help - would be great to add at least one potential 10+ sack guy and another young guy with upside (preferably two) and Merci needs 7 or 8 sacks a year to justify that contract
Right Guard - really need to strengthen that side of the line and make it a run defenses nightmare - just a guy looking to crush someone
After that it's depth;
Think they have a few backup LB's that have been in the OK/MEH range and have had a few years to prove themselves (and haven't) maybe keep Cole and find another guy or two (I personally like the idea of finding a really good coverage LB - or just draft a big safety with coverage skills and tell him "hey kid, you're an LB now"
OL depth - would be nice to grab a young center with upside and move on from Martin next year if he doesn't play better this year (I think THEY like his smarts or what he brings to the locker room - I don't like the pretty continual 5 or 6 yards he gives up straight back on most pass plays) R Johnson might continue to improve and be a quality / decent swing tackle who can spot start - but would still like to see them add some competition
DL depth - if they don't sign Reader, add another big fella with a focus on pass rushing and rotate them with Dunn, Blackson, Charles O, etc.
So realistically they need to;
hit on 1 (preferably two) high priority FA's, 1 CB and 1 Pass rusher would be fan-frickin-tastic
add two mid-tier FA's (right guard here would be nice)
two draft picks - 1 that can be a solid starter (RG or CB potentially) and one that is a borderline starter and/or plays significant snaps per game
use the remaining picks on depth (OL, DL, ST, LB)
and scour the rest of the FA's, cap casualties, waiver wire for people that didn't fit their old team's system/style buy you think fits yours
I like this plan, I think they add Harris and re-sign Roby, plus add a CB in say the 4th rd.
Reader will be gone and using the $$$$ from Reader allows you to sign Harris. Roby's FA $$$$ comes from JJo leaving and you would have $$$$ left over from the existing cap to sign a DT. Suh or Linval Joseph who got cut yesterday would be a good replacement. Then adding a guy like Elliott or James Lynch in Rd. 2 and you would have a much improved CB/DL room. That would leave you needing a big nickle and this is where I would use my 3rd and the Texans 4th to try to trade up to the bottom of the 2nd/top of the 3rd if Dugger/Chinn fell.
The rest of the draft would be spent on WFV insurance/RG/RB.
I'm not saying my way is the only way to do things, but these moves would really help the defense.
