Thanks so IMO looking to be a 3 -5 year turn around ....
Haven't been following the NBA for long enough to really comment ... but take away any of their top 5 starters and they still lack the bench depth IMO ...
I think that the main diff. between the NFL and NBA is squad sizes.
An NFL team can lose almost anyone and still be competitive, sometimes even SuperBowl winners - as Philadelphia proved in SuperBowl LII. They lost their starting QB, Wentz, in wk.14 but Foles took over and they went 5-1 including 3 straight in the play-o***.
Plenty of teams have won the SuperBowl without a Hall of Famer QB: Baltimore under Flacco in SuperBowl XLVII; the NY Giants with Eli Manning in SuperBowl XLII and XLVI.
I'd never deny the value of a good QB but it's a bit different to the NBA where I think that one star can compensate for much. A star QB can't do it without a decent O line to protect him, at least one decent WR who he can target and a defence that can limit the amount of points needed to win. Think Aaron Rodgers.
Look at the teams that have lost QBs this year:
New Orleans - lost Brees for 6 games but went 5-1 in that period
Carolina - no Newton since wk.2 but 5-1 under Allen
Indianapolis - no Luck from the start and arguably only lost last week because of Brissett injury but with a 5-3 record
Pittsburgh - lost Roethlisberger in wk.1 and 4-4
Coaching really helps, too. The LA Rams were a basket case under their previous coach Jeff Fisher. They didn't have a winning season in the 5 years he was coaching them and had a 34-45-1 record. Sean McVay took them to 11-5 in his first season. It was their first winning season since 2003 when they went 12-4.
