How did the giants improve? Seriously
Quick answer:
Second year in the Daboll / Martindale system. (this is the biggeee)
Improved their DL rotation. They had a strong front line with Dexter Lawrence and Leonard Williams but they added 2 strong players in Rakeem Nunez-Roches and A'Shawn Robinson. On paper this is a step up. While we're on defense they added LB Bobby Okereke who is strong in the middle. Weakness will be 2 rookie CB's but they strengthened their front 7.
We'll have to pass on them I think.
On offense they'll probably be the same on their OL (I don't see any meaningful improvement) but Danny Dimes looked better last year that I've seen him so Daboll is obviously behind this. Barkley playing for another contract. Improved markedly at TE and at least have some decent WR's this year vs 2022.
Here's your Cliff Notes.
