to me it doesnt look like a great "big body" class - and even those boundary, good at the catch-point guys aren't all that big this year anyway
Rashod Bateman is 6'1 210lbs and an exceptional route runner with a penchant for making incredible catches who tracks the ball really well (im super high on Bateman)
Ja'Marr Chase is 6'1 208lbs who's about as dominant at the catch-point as ive seen from a college prospect, he's got some route-running deficiencies (and problems getting off press) right now that would need development but he's a very explosive athlete with tons of tools to be very successful - he plays a lot bigger than his size
Terrace Marshall Jr is 6'3 200lbs and has the prototypical body and athleticism and quick feet that any team would want at the position - but he had a few drops in 2020 (although tbf i dont foresee that being an issue in the NFL) - but he's not a good route-runner right now and doesn't create a ton of separation - seems to do his best work out of the slot (which is obviously not who you're looking for on the boundary lol)
Tylan Wallace is 5'11 193lbs which obviously isn't the frame that you'd normally expect out of a boundary receiver - he's a good route runner and really successful at the catch-point (great hands, body control, ball-tracking etc... makes some crazy catches) - there's some athleticism question-marks about him but he seems to threaten DBs vertically on his tape which suggests he's not going to be limited by that in the NFL
Cornell Powell is 6'0 200lbs is a really interesting prospect because he hardly played until this year for Clemson (tbf he's been stuck behind a ton of receiving talent) - so there's not a ton of examples of him making contested catches on the boundary but he looks like an interesting outside WR (i personally like him a lot) - he looks good against press, is a really nice route-runner and got good hands and he's physical through his route - just such a limited sample size vs most of the other prospects in the class
Frank Darby is 6'1 200lbs who plays bigger than his size - he's physical, tough, competitive - doesn't have blazing speed but seems to be able to stack well vertically - good hands and he's aggressive at the catch-point - he seems to struggle decelerating and breaking back towards the QB which gives corners the opportunity to close on the ball underneath - but otherwise his route running is pretty nice
There's some other guys but these are probably the top options:
- Seth Williams is highly regarded by some but I've got a ton of issues with him as a prospect - seems to me to have low effort and some moments that suggest to me he has poor awareness and not a ton of intensity either
- Ihmir Smith-Marsette is really raw and not the best playing through contact - probably a gadget guy/slot early - really suffered from awful QB play which makes him hard to evaluate
- Austin Watkins Jr has prototypical size and some nice route running and nice ball skills but doesnt get a ton of separation - he probably fits your mould quite well
- Dez Fitzpatrick is a nice athlete albeit not super-twitchy with some intelligent route-running - fights through contact through his routes and adjusts well at the catch-point and has good hands - tends to fade in and out of games (might be because of awful QB play) - fun fact though he played with Lamar in 2017 - he was the standout receiver in the senior bowl game
- Trevon Grimes has the kind of body and playing style you're talking about - ive got a lot of questions about his long-speed but he's got some nice nuance to his route-running and carries speed well through his cuts - could become a nice pro especially in a possession receiver type role (not sure how effective he'll be vertically at the next level)
- Josh Imatorbhebhe is an awesome athlete who offers size and length and explosion both downfield and the elite ability to elevate above the rim and high-point the ball - super raw prospect - he's about as developmental as a prospect gets - but an absolutely outrageous athlete especially his vertical jumping ability
- Tamarrion Terry is again a crazy athlete for his size especially his lateral quickness and he has a massive wingspan - but there's a ton of body catches on his tape and drops too - and he seems to shy away from contested situations (not sure how much he relishes contact) - seems to be over-thinking during his routes - another developmental guy
- Josh Palmer has a great catch radius and great hands but looks like a pretty limited athlete - he's good fighting through contact during his routes but that's because he doesn't seem to be able to separate
- Sage Surrat uses his body well to create leverage at the catch-point and tracks the ball well - limited athlete - despite his size seems to get beaten up vs press - seems to have the mentality after the catch of someone smaller than him - has some route running but idk that he's good enough at it for it to be a calling card - not sure how he'll win in the NFL
- Simi Fehoko has a huge frame and maybe has some build-up speed in a straight line - some drops and some incomplete passes down to lack of awareness on the sideline and some body catches too - generally good hands otherwise - better vs zone than vs man - CBs sit on the underneath stuff because they aren't afraid of him vertically
everyone else who could be a big body boundary type that ive watched has ended up with a udfa grade i think - and some of the above guys might be udfa grades when i finally get to more of their tape later in the process
TL;DR... that's probably more detail than you were asking for lol but those 16 names are the ones to look at if you're looking for that type of receiver but I'd personally start with Chase, Bateman, Wallace, Darby, Seth Williams, Trevon Grimes and Sage Surratt (i personally am not a fan of Williams or Surratt but many do like them)
