How great was Stafford's cast last year? Kupp and. . . . .um, nobody. I guess Odell a tiny little bit but Odell was solid because of Kupp. He's not great.
Outside of that, literally not a usable RB on the entire roster for nearly the entirety of 2021, to the point where they brought back Akers from an achilles 4 months after he tore it. Dak has CD Lamb, who is elite. He's got a phenomenal TE, although Schultz did give up at the end. And, obviously, he's got two excellent RBs to hand off and throw passes too.
Dak's supporting cast is better. The coaching is worse.
You're underselling Stafford's help this year, mostly because Kupp is that good. Dude had 145 catches, almost 2,000 yards and 16td's (IMO, the greatest season in history for a WR). But what he also does is free up the rest of them. Robert Woods was on pace for about 85 catches, 1,000 yards and 8 td's when he got hurt in week 9. Jefferson then stepped up. Even with Woods going down, he and Van combined for 95 catches, 1,358 yards and 10td's. Higbee got 61 catches.
Jefferson got hurt this season, and missed the first half of the year, and then they brought in the washed up Allen Robinson to replace Woods, which didn't work. Then he got hurt right around the time that Stafford and Kupp got hurt and Jefferson was out there by himself. But even before that, their defense was a mess early in the season, and it was over for them.
I agree Dak's cast is better.
If we're talking about the casts around Stafford in 2021, and Dak in 2022, to give them some benefit of the doubt, Mac deserves about 5 helpings given the cast he was playing with (and coaching staff and offensive line).
