If Marinelli is the one making decisions on draft personnel, then McClay is free to walk. That's his job.
I guarantee you he's not the one saying Rod's making his decisions for him.
Dallas follows the consensus from Garrett, Stephen, McClay, the scouts and the rest of the coaches so much, I think it is pretty much impossible to say who is really is making the personnel decisions.
Is it McClay? I mean, partially... but he closely adheres to Garrett's RKG wishes. Garrett and Stephen both want physical, tough players who love to play football. That's the kind of guy they draft... particularly with high picks. Marinelli wants guys with high motors (which also follows with Garrett's RKG). That is the kind of guys Dallas drafts. Linehan loved Dak.
They all have so much input (particularly Garrett) that to say McClay has been great drafting is folly. It is all of them. Really, it is Garrett's vision for the type of team and type of player that the team drafts to, and it is the driving force behind most of the teams recent draft success.
We simply have no idea who McClay would have drafted without all the input from Garrett and the rest of them.
Free agency would be the same. Any player will have to adhere to Garrett's RKG guidelines and will have to be a high character guy (they learned their lesson with Hardy). He would also have to be young enough to play out the contract while still in his prime and the front office (Stephen) would have to think any high price free agent is at least close to worth what his open market price is (because they won't grossly overpay for free agents as they've said numerous times).
All of that is very difficult to find in a high priced Free agent. First off, most of those types never hit the open market (like Berry this year or Dez a couple of year's ago). Their original teams just don't let those guys get away most of the time. Usually, there are some issues with the guys that are available... like they've gotten too old or they have off the field issues.
If someone does fit the guidelines Dallas follows, then they are usually outrageously priced like Vernon or Jenkins this past offseason. And while Dallas isn't in cap hell and they can spend big if they wish... there are teams that have crazy money available and will spend it. It makes no sense to get in a bidding war for someone like Vernon. Like Stephen said last year... you pay average talent like it is really good and good talent like it is elite. That is just bad business. It is going to come back to bite the Giants that they spent that huge. It was just Reese's desperation that caused him to spend it. He couldn't draft good players so he just over spent like hell to get some.
Vernon had 8.5 sacks and 1 forced fumble as a starter while David Irving had 4 sacks and 4 forced fumbles in a rotational role. Irving cost next to nothing and Vernon cost upwards of $100M. That's just not smart.
So, while some might say that it isn't important to name who Dallas should get from the defensive free agents... that we should just let McClay spend to get some good one's... I think the issue is exactly that: Who is even going to be available that fits their criteria and is good enough to even spend big on. There aren't going to be many of them out there, if there are any.
I would love a big time free agent pass rusher too but there is a whole lot going against Dallas doing it... and that starts with who will even be available.
