I'm not worried about Maye. He's 23 years old and it was his second season. And even his rookie year was muddled with a later start due to Brissett starting, and coaches like Mayo on the staff.
I'd like to think it's a wake up call for him though, and also the front office + ownership that they need to continue building. The roster probably overachieved and benefitted from an easy schedule. Doesn't mean they can't get back to the SB, but if they think they can just status quo it, it won't work even with Maye.
Also Maye did go up against 4 of the Top-6 defenses in the entire NFL on this postseason run. Kind of tough luck, although some of it was offset by Nix being hurt and Stroud just being horrific.
For me the BIG concern is still O-Line, especially LT. Campbell was outclassed in the postseason and I don't think much will change sadly on that end. He's just not built to last long term there against these young/fierce pass rushers. Wilson can be our long term center. Campbell I think can be an excellent left guard. But they need an LT and some more depth on that line. Even Brady and Mahomes struggle in the playoffs with poor O-Line play and Maye was sacked like 21 times this postseason, even more than Burrow 4 years ago (yikes)
