The Rams sent a team, a stacked team, and won. Stafford has always been good, but on a poor team. He, and the Rams in general, show us important lessons.
Yes, the obvious first: Kirk and Stafford are very similar in style, stats, etc...and both are very good with a couple of seconds to work with. The Lions have been a mess for ages and we haven't actually had a QB-centric offense since Favre (briefly) and since Culpepper before him. Just the coaching upgrades, combined with some addressing of our OG/C play, should make a good group genuinely terrifying.
Defensively, the Rams have half of the talent in the NFC, and that will be a bigger fix. Zimmer/Spielman somehow managed to spend a huge amount of money on players that would be hurt/ineffective and leave us with pretty scattered elements to build with. I'm a huge fan of Harry, but he's a better field general than he is an open-field tackler, anymore. Kendricks is amazing, but I'm not sure about any other remaining LBs. The D-Line is a row of question marks, especially with Hunter possibly wanting out...and, honestly, what is his actual worth if he is truly fragile, now?
I don't pretend to have the answer to that.
Patrick Peterson is not an 8-digit corner, but at the right price I'd want him back. In fact, the remaining secondary should be coachable, and that'd be an area I'd be interesting in drafting for.
Anyway, yeah, that's how I see it. The Rams went all in, they can't really afford to keep everyone...but they got a ring. I hope we find a way to get the title AND keep it sustainable for a good, long run.
