There's only 1 Kelce.
Waller has the greatest chance to be #2, IMHO. My con to Waller is the development of Ruggs/Edwards/Renfrow and addition of Drake/Brown. I think Raiders passing O aggregates will rise, and potentially be more diverse.
Kittle has a great chance to be #3. My con to Kittle is, will he play close to 17 games, the potential for instability at QB, and the addition of Sermon, who I view as the most complete back they've had in a while, upgrading the RB corps (Mostert/Sermon/Gallman/return of Wilson) over previous stables.
Andrews is my solid #4, with #2 upside. The Bateman injury seals the deal for me on this. Every draft I pray Andrews falls to me in the 5th. At that point, I would pass on RB/WR to Roster him. Rarely does he make it out of the 4th, so most of the time I'm not landing him.
Pitts is my #5, but I'm not drafting him at his ADP. The offense Atlanta is installing is very Matt Ryan friendly, and I'm drafting Ryan as a QB2 in many places. I personally like the Falcons skill position players: Davis/Ollison/Patterson etc./Ridley, Gage, Zaccheaus, etc./Pitts/Hurst. I think there's a lot of potential there for the whole being greater than the sum of it's parts. That being said, I'm not investing a high draft pick on a Rookie playing a hybrid position. I am, however, drafting Hurst, very late, in many places, as a TE3 flyer. I think he has some serious upside vs ADP.
Hockenson is my #6...right at this moment. He could move up as far as #3, but at this moment I have no reason to put enough faith in Goff's ability to max utilize all the other pieces that will start in that offense to invest at ADP. I like what I've seen out of St. Brown in the slot. I like the potential of Swift/Jamaal in the passing game. However, all of sudden, that's a bunch of bodies occupying the same target zone (within 10 yards of the LOS). I'm a big fan of Tyrell Williams, but I sure wish he was the #2 to a bona fide #1, and I don't think Goff/Tyrell is an optimal pairing anyway. At that point, he becomes little more than a field stretcher. Cephus, Raymond etc. are nice players, but not special. I've heard reports that Perriman hasn't done anything to distinguish himself. What that tells me is that defenses will squat on the short-to-intermediate zone, and limit access. So, to draft Hock, I'm betting on Goff, which is distasteful in and of itself, and that he'll get enough target share when Goff is being forced to choose between him/St. Brown/Swift/Jamaal, and that Goff can wing it to Tyrell with some degree of success. Way too many 'what if's' for me.
So now we're into the next tier, and my preference here is to draft Higbee in the 8th, if possible, (unfortunately sometimes the 7th, grr...), and Everett in the 12th (11th if I have to). IMHO, these 2 are the most likely to finish at the top of their tier. I'm very high on the McVay/Stafford offense. Subtract Reynolds/Everett, upgrade VanJ, add DJax. I'm not worried about Jacob Harris, Bryson Hopkins or Tutu Atwell. Higbee should be targeted liberally all over the field.
I think everyone else in the tier has warts I can't get past, right now.
Thomas: I'm as big a WFT fan as they come, but I'm a realist. There is no such thing as consistency from Fitz, and there are way too many mouths to feed in the 21 offense. No, thanks, in the 6th-7th.
Fant: I see zero reason to trust the QB situation there at all, right now. It could rotate all year. No, thanks, in the 6th-7th.
Goedert: Hurts/Ertz. No way in the 7th-8th.
Tonyan: my Higbee fallback in the 8th, but I still worry about Jones/Cobb/Amari clogging up target share in the short to intermediate zone, and TD's are unpredictable.
Irv: I have some shares of Irv, and I like the player. I just don't like Zimmer or the offense they run, which refuses to let Kirk cook until the Vikings are in desperation mode. I might take him in the 9th if Higbee goes early and I pass on Tonyan because something else falls, but won't be thrilled.
Gesicki: WE ARE!!! ... but I don't trust Tua. No way, no how, (fastball has) no velocity. Fuller wasted here.  If Brissett were elevated to starter, I'd be more confident. That's how little faith I have in Tua. No fish for me in 21.
Jonnu: I have some Jonnu, but now he's banged up, and so is Henry, and those are the only legit weapons in this passing O, IMHO, plus I don't trust Cam, and don't want to rely on Mac with that surrounding cast. If healthy, has some upside.
Engram: chronic underachiever, Golladay out for a bit, Saquon not 100%, putrid O-Line, Daniel Jones. Way too much risk for me.
Trautman: love the Player, but don't like QB roulette, or the QB's involved in it. No Thomas. Whole O looks like a mess. If he's on the WW mid-Season and Ian Book becomes the starter, I'd take a cheap gamble.
Everett: Ah, now here we go! TE17 in the 10th-14th round. Comes from Rams along with OC Waldron. No 3rd WR option credible enough to sap targets from the most athletic TE the Seahawks have had in I don't know how long. There's no comparison between him and Will Dissly/Colby Parkinson. If any of the bottom of this group has a chance to post a starter-worthy stat line, it's Everett. 
Cook: At his age, lacks 'dynamic', and what's left after Ekeler/Allen/Williams hog up most of the targets in this version of the Saints offense? I don't see nearly enough volume to sniff TE12, which is the floor you need to make any of these guys worth drafting.
That's through TE18
Sure wish Jarwin/Schultz were one person. Same with Gronk/Howard/Brate. Same with Doyle/MAC/Granson.
I'm taking a flyer on Hurst in the 18th-20th everywhere. He's being ranked in the 30's. I strongly feel he can finish as a mid-to-low TE2...but what does TE 16-24 get you, really? There's a path to him doing better than that, but it's mighty narrow, and would require a lot of things to break right, but he is the traditional TE in the offense, has chemistry/trust with Ryan, can handle Red Zone work, and won't be clogged up with blocking duties while logging a massive % of offensive snaps.
Higbee has it, IMHO. TE9 who can flirt with 4-6, preferably in the 8th. Tonyan, maybe, TE11 who's safe to finish inside 7-12, preferably in the 8th, if Higbee goes early. Irv, TE12, in the 9th, with a grimace, but realistic shot at finishing inside 7-12. Jonnu, TE14, if healthy, in the 10th, same deal, 7-12. ***Gerald Everett*** TE17, around the 12th, 7-12 upside. End of draft flyer on Hurst.
...and that's what I have to say, about that.
