Which part of what I said (that most people seem to agree with) is your retort supposed to be aimed at?
The part I quoted mostly, but it also applies to your entire premise.
Let's review:
Emery can either maintain his already existing 4-3 defense that just needs a MLB and keep a system all his existing players are very experienced in.
Or he can switch to a 3-4 and and play his entire defensive front (except Shea) out of position in an totally different system while he wastes more picks and FA money trying to find a real NT, DE's, and LB's that actually fit the scheme.
Who the **** does that? Especially when it's glaringly clear to everyone except Cutler haters that the problem this season wasn't the fucking defense. You don't switch to the 3-4 on a whim because it's what all the cool teams are doing. How about we fix the weakest link in the chain instead of hacking up the good part because a handful of meatballs thinks it'd be cooler if we ran a 3-4. The weak link on this team is the OL.
Folks need to take Cutler out of the equation and look at the OL objectively without the hater/homer glasses on. Compared alone to the defensive line it's not even close talent wise. Webb is fucking terrible. Practice squad James Brown should not be starting at LG next season. Garza is overmatched at C and old. Louis is coming off a blown knee. Carimi is even worse than Webb. You need 4 new starters across the board (5 if Louis can't return to form) regardless of how serviceable you think they looked the last 2 weeks.
The #1 priority this offseason should be hiring one of the best offensive HC canidates you can get and putting together an NFL quality OL capable of playing on the defenses level and not blowing up the defense and installing a 3-4 with a bunch of guys playing out of position and regressing them down to the OL's level.
