I assume you meant 2029, because Dak will play in 2028 under his current contract. Unless some catastrophic financial event happens in the NFL by then, his $60MM/yr will look like peanuts.
Hopefully we've gotten to the NFCCG by 2028 and all the nonsensical talk about Dak will stop, but it won't, not even with a SB win.
I think he's a Top 5 QB, but let's say he isn't and is a Top 10-12 instead. QBs in that tier are incredibly difficult to replace, hence the big contracts these guys get. It makes him one of the 12 best QBs on the planet playing an incredibly difficult position, both physically and mentally.
The OL help is a big deal for Dak (and the run game). Extrapolated out over the entire season, he was in the Top 10 of most sacked QBs last year and in 2023. Historically, he doesn't take a lot of sacks. Less time to throw the ball = more incompletions and less accurate passes, not to mention an array of receivers that nobody is writing home about other than #88.
I know the anti-Dak crowd here - including you apparently - want to lay every loss on Dak Prescott. That's cool. When people espouse that opinion, it lets everyone else know where their knowledge of football lies.
