Their stats are similar but that just shows how thin the line is between QB's at this level. I think a lot of fans are basing it on when the lights were on and the game came down to it, Williams and the Bears just couldn't get it done, at least not consistently as much as Daniels and the Commanders did.
The Bears were 3-7 in one score games with 2 of those wins coming against the worst team in the league (Titans in Week 1 where the offense scored 9 points, 0 TD's, and only won due to 2 defensive and special teams TD's) and a team that their starting QB played 1 quarter in Week 18 (Packers) and didn't need to win anyway since their playoff seed was locked in.
Meanwhile Daniels and the Commanders went 8-4 in such games and won another one on the road in the playoffs before going on the road again and dismantling the #1 seed in the conference.
In those 10 one score games, Williams and the Bears had the ball inside of 2:00 left in regulation or in overtime either trailing or tied with the opportunity to win it in 6 games. Only once did Williams pull off a game winning drive (the Week 18 game against the Packers). He did have a few potential ones ruined though: one a blocked FG to win against the Packers, one by none other than Daniels himself, and another against the Vikings where they drove for a FG to tie then failed to score again in OT.
For Daniels, he and the Commanders had that same opportunity (tied or trailing with < 2:00 in regulation or overtime with a chance to win it) in 6 games as well (and another in the playoffs) leading 4 game winning drives (5 counting the playoff game) and having another potential one blown by series of special teams implosions including a missed XP (which would've tied it) and the ensuing onside kick being returned for a TD resulting in them losing instead of the opportunity to play for overtime.
While I don't think Williams outright "sucks", he had quite a few head scratching moments this year that makes it appear that he still has some significant growing to do in the league whereas Daniels started a little slow then acclimated an played admirably.
Guess we'll see how both do once in Year 2 now that defensive coordinators have that full year of game tape on them.
