I think the idea is you want to give Caleb his signature guy to develop ESP with - that kind of communication because you grew up in the offense together, and you already know what the other guy is thinking.
In the 70s and 80s there was always that stud receiver paired with the star QB for multiple seasons.
If Poles is looking long term, then he loves Keenan Allen for giving Caleb a jump start, but he looks at that position as a hole long term.
So this is our last top ten draft draft for a while. You want to use it on an impact position, which is QB (already done), Pass Rusher (including 3T), OT or WR. So you ask yourself not just what does the roster need this year, but who are my pillars for the next 10 years.
If you think one of the WRs is a game changer, you take them regardless of Allen being on the roster.
If you think there is a pass rusher who will take over games, you take him.
If you think there is a left tackle that will keep Caleb clean for the next 12 years, you take him.
So rather than looking at position and this years roster, ask instead, of the D linemen, WRs and OTs, which player is truly a difference maker. If you think Jared Verse is an edge rusher that can take over games and make Montez Sweat DE2, then you grab him. But if he isnt that, but some OT is, then you gotta go with the most talented game changer regardless of position.
Maybe thats an argument for Bowers, or for trading up. Or maybe someone thinks Fashanu or Turner or whoever is that guy.
But that's the point - whos the best impact player you can get, not what fills a roster hole in 2024 a little better?
