Last year, Seattle
Team rushing attempts -- 8th from the bottom at 425= 25/gm
Team tgts to RBs and 8th from the bottom at 84 = 4.94
Rushing TDs per game 0.7
Let's assume they wanted to run more but they didn't have the player health that they'd envisioned and their ideal script would actually be more like this:
Attempts= 28 (would be around fringe top 12 in attempts per game)
RB Targets=6-projecting a slight bump but still bottom third of the league.
Team rushing TD/gm- 0.9 is exactly a mid pack expectation from last year = 15.3 on the year.
Total team rush yards around 130 per game would have been #10 in the league last year. They were 18th at 119 last year.
Prioritizing a high quality RB in the second round suggests they have a role in mind. The fact that Charbonnet is considered a good compliment in addition to quality depth makes sense. Maybe this is a bit too anecdotal but I see Walker as an explosive back with a low success rate and Charb as their vision for a guy that can catch passes a little better and have less explosive but higher success rate runs. IE goal line and short yardage situations.
If we imagine how Seattle sees using them and divvy up the carries, targets and TDs we get something like this:
Walker 16 for 75, 1.5 targets for 1 catches, 7.5 yards and .35 TDs
7.5+1+.75+2.1=11.3/game
Charbonnet 10 for 46, 3 targets for 2 catches, 15 yards and 0.50 TDs
4.6+2+1.5+3=11.1/game
That leaves 2 carries, 1.5 targets and the odd rushing TD for the other guys. That's probably too low (for the other guys) but if they've got their lead guys maybe they'll just pug 'em in.
That leaves them both firmly as RB3/Flex guys. And of course if the TD rate spikes to an outlier-esque number, great. Last year phi was 2.1, Detroit was 1.4, Dallas and the G men 1.3 and SF/CLE/CHI/MIN were all 1.0. Projecting more than 1.1-1.2 seems not realistic.
If you don't agree with that projection, be my guest and fill in the blanks different. I'm no Seattle expert so if you think you have insight into a different intended usage of these guys, knock yourself out. Personally I won't be prioritizing either one until the 9th or 10th in redraft with the obvious caveat that if one gets hurt, then, they will likely not use one or the other as a 23 carry/ 5 target guy and end up being a back of the RB1 tier guy. Great but not vintage CMC or Derrick Henry.
