B - if any NFL team alters its value of a player by what he does in a bowl (ie - ONE GAME), then they're probably a dumpster-fire of a franchise

Chuba played in 13 games last season - in 7 of those games he had 7 or fewer carries
Chuba played in 12 games this season

so 18 games with major contribution - not all of those 18 games were against solid competition

one more game vs solid competition is significant for evaluation

I mean teams hold pro days, which is a more pointless version of a pointless event, and scouts attend.  I'd prefer a bowl tape to anything learned there.

Well a pro day is sort of unique, isn't it?  A bowl game is just another example of something you have on film plenty already. 

Idk, personally, the success or failure of a draft pick on any given team is much more random chance/luck than anyone involved would like to admit.

A pro day is basically so scouts can check off what they already know or cross people off lists. They mostly learn nothing new (unless it's like a snapper or something).

And yes, it's often luck based. Same as coaching hires to a degree. 

If a player goes off with a trainer and works on his "40 times" and shuttle time, etc., as opposed to practicing for a game, how much can he realistically improve his statistics?

Maybe a player, an OL, DB, LB works to shed a few pounds and comes out faster than expected in the 40, does that elevate his draft position?  Obviously, this can means tens of thousands of dollars, in theory.  

I thought Nick Chubb was a 'sure thing" mainly because of his character and work ethic.  He seems to be doing pretty well at Cleveland.

Those personal attributes can't really be improved and I value them a lot in a player.

Looks like "just" three players

ATHENS, Ga. -- Georgia will be without a third starting offensive lineman when it takes on No. 7 Baylor in the Allstate Sugar Bowl on January 1, 2020 (8:45 p.m. ET on ESPN). Fourth-year junior right guard Ben Cleveland will miss the bowl game due to academic issues per his father, Derek.

So say Baylor beats UGA.  I tend to look at the other side of the "UGA was down a few players" and/or "they didn't show up" ideas - unfortunately, it would cheapen the potential victory for Baylor.  Yes, they get the win, it goes down in black-and-white and all, but for us who are around now, we know the win wouldn't be 100% strong. 
Which sucks.
