Here is the 247 profile that shows he ran a verified 4.38 in HS. Sorry but I can't locate the source that I saw as showing him running a 4.35.

He was the Florida Class7A player of the year in his senior year. They went to the state championship while he was there so he saw plenty of talented Florida DBs who are typically as talented as any DBS in the nation and go on to be some of the best DBs in college. He had offers from Alabama, Georgia, Penn St. and Ole Miss. So it is not only I who believes he can be a game changer. A 4.38 is more than sufficient to smoke almost any DB in college on a go route.
2019 Receiving Stats: Receptions/Yds./Avg.
Gabe, 72/1241/17.2
Marlon, 51/717/14.1
Tre, 49/830/16.9
So last year Gabe had 72 receptions. Since those touches go away I believe they will be shared by Marlon and Trey mostly, although of course Flash and others make get some of those touches.
I agree with you that maybe Tre does not get as many receptions next year as Gabe had last year, given that he and Marlon will both be likely to share the leadership role as receivers. But I think Tre's increase in touches will likely be greater than the increase in touches for Marlon since Tre is more likely to be our go-to deep threat due to his speed.
If you compare the yards-per-catch from last season, the 2.8 yards-per-catch difference between the two is a 19.8% increase in yards per catch in favor of Tre. So Tre clearly is more of a big-play guy than Marlon. I also agree with you in regard to your estimate of the yards that Tre may end up with for the season. I think 1200-1400 seems about right given the number of weapons who will share the luv.
I think they are both very good receivers but with different strengths. Tre is likely to be our best deep threat. Marlon is a sure-handed and powerful underneath and across the middle type receiver who can overpower defensive backs to get additional yards after the catch.
I think Tre and Marlin will both have very successful years this upcoming season. I am excited to see how they can complement each other on the field. Not to mention the elusive skills that Flash will also provide. It could be an exciting season with DG getting multiple guys involved.
