Carroll never had to deal with the QB, and other injury problems Fishers has had! That makes a Big difference! As to Carroll's Roster Turn over I'm not sure your right or wrong.
The QB situation is all on Fisher at this point. Bradford showed himself as injury prone
last year. I remember having a debate with people on this site about how he was injury prone and the Rams HAD to do something about the QB situation. They didn't and now they're suffering for it. I recommended Garappolo and even considered Bridgewater as a possibility. I even said to trade down(Buf offered) for the extra first to have ammo to trade up for a QB this draft. I didn't want much after Garappolo or Bridge because I'm not big on project QB's; I didn't consider those two to be much of a project. Most of the media last draft season were saying the Rams needed to do something about the QB situation and the Rams still refused to address it. So when Bradford went down AGAIN, it became a problem with Fisher, not Bradford. Fool me once, shame on you. Fool me twice(more than that, actually), shame on me(Fisher).
You can say Garappolo or Bridge probably wouldn't have helped much last year but I'd be willing to bet they'd help this year if/when something happens to Bradford. Even if Bradford manages to go the entire season next year, do you feel comfortable signing him to a new, long term deal? I don't. Having Garap or Bridge would have eased those concerns. Now the Rams will be looking for project QB in a horrible QB class. Good luck with that, Fish.
As for the roster turnover, it's been mentioned on the local radio stations in previous years that since the start of each team's respective rebuild, the two have had the same amount of turnover. They kept the same amount of players(or very close) from the previous regime after three years. Since I couldn't find any site that had the info ready, I had to go and compare the rosters they inherited to year three of their rebuilds (just for you, Dave). The Seahawks kept 7 players from the previous regime to year three: Butler, Branch, Mebane, Obomanu, Ryan, Trufant, and Unger. The Rams kept 8: Bradford, Kendricks, JL, Long, Quinn, Saffold, Sims, and Pettis. Only one player difference, which, IMO, is irrelevant.
My point is, the two have done virtually the same amount of roster rebuild but one team had an 11 win season by year three and won the SB in year four. I'm not saying Fisher is crap but he isn't a savior either.
