The best comp for Fergs is Gerald Everett. I can’t find it but I’m almost positive he played in preseason. Either way it’s too soon to call which rookies will sit or play.
I get that you don't like Fergy as a pick but Gerald Everett is a terrible comp. Way off on that one my man.
Everett is an undersized TE whose raw athleticism doesn't translate due to him demonstrating shit like halfass blocking, poor hands, lack of give a fuck over the middle, poor instincts in space, sloppy routes, easily redirected by safeties, etc. Not saying he does all those things consistently. But lack of consistency is also a drawback for him.
Fergy is a full sized TE with good hands and movement/athleticism and a completely different profile of drawbacks. He needs a ton of work on his blocking, but the Rams aren't going to use him as an inline blocker as a rook. He'll be in there as a slot option when they want a big target over the middle or like his mismatch vs that defense. They'll scheme up some touches for him I am sure as well, because he doesn't look like he's fast but he's fast and can roast you on wheels and crossers.
I think the upside comp for him is Kelce. Kelce of course is best case scenario, but they have a lot of similarities in raw skills and if Fergy can clean up his route tree watch out. Also Fergy is benefitting from a great offensive mind in terms of scheming him open. And McVay has been pining for a real TE for years now so he's going to pour into this kid.
