2021 NFL playoff predictions: Five teams from 2020 postseason that will miss out and five that will join party

No Aaron Rodgers means no postseason in Green Bay and Dak Prescott's return lifts Dallas

By now you all know the mantra about the NFL being a league of parity and opportunity and all. You know the drill -- every year about a half-dozen new teams make the postseason, and a half-dozen or so fail to return. With an expanded playoff field now, the chances of turnover remain quite high. Might as well get cracking on how that turnover might take place as we start to kick off some OTAs around the league. Of course, it's always debatable just how much gets accomplished in these sessions except for the most neophyte of player, and this year veterans are vowing to stay away in droves, but it is another benchmark in the NFL calendar and an indication that we are inching close to the start of training camps this summer. I have to be honest, there were not a ton of teams screaming out to me as being suddenly playoff-bound, and some of the more obvious candidates (i.e. teams that just missed out a year ago) like Miami for instance, have me wondering if a step back is more likely than a leap ahead. And sometimes, you just can't overthink it -- when a team is getting a top 10 starting quarterback on its roster after playing most of last season without him, well, that team is clearly a candidate to at least sneak into a watered-down playoff field in 2021. I found myself having, in general, an easier time coming up with 2020 playoff teams I would fade than I did coming up with five teams I thought would certainly make a jump up. And in the end, we all know a few injuries and some bad luck, and a season could unwind in any number of ways. But here are some teams I believe are primed for a fall from a playoff perch, and five I am at least somewhat bullish on to leap forward. Titans: They seem to be preordained to win nine games or so a year and get into the big dance. But that run ends now. Too many questions about that defense -- which was already poor a year ago -- and too much brain drain from recent coordinator defections and too many departures and injury questions on offense. This ain't the same group up front or on the outside that helped Ryan Tannehill revive his career, and the loss of Arthur Smith drawing things up will prove massive. Will struggle to defend the big play, and also struggle to produce as many of them as they once did. Derrick Henry's workload will catch up to them at some point, too.
