I don't believe I ever debated who the better player was, but take out the TDs against the Texans (and remember Lewis had 0 on the season before then), and Lewis had a pretty unimpressive game. A 3.15 ypc and 64 yfs is not exactly a fear factor for opposing defenses. Fantasy wise, 64 yards would be nothing without the TDs . . . and 2 receptions is not exactly killing it in PPR scoring.
So to come full circle, yes, Lewis will see more snaps and more touches than White, but if the touches are predominantly rushes and not receptions, we need to reevaluate how valuable Lewis is for fantasy purposes. He only had 8 catches in his last 5 games. He also only broke 100 yfs once in 8 games. Yeah, I get that he was coming back from injury and they were saving him for the playoffs, but his usage and role doesn't seem to support him as a great fantasy asset, and how many 3 TD games (1 on a return) can we reasonably expect from him?
My takeaway from that game was not in the production (TDs, ypc, rec, whatever) but in the usage. A single game's production for a veteran player means nothing in the long run - do you really expect Dion to have 3.15 ypc or a 29% catch rate in a 16 game season? Of course not. But the fact that he got 13 carries (led the team), 7 targets (2nd on the team), played 48% of the offensive snaps,
and got a goal line carry in the most important game of the season (so far) does carry some significant weight. That usage and role absolutely DOES support him being a great fantasy asset.
The fact that James White got 86 targets during the regular season but only one in this game also carries some weight.
Dion only played the last 7 games of the regular season and was brought along slowly (they won all the games so it's not like they needed to lean on him). His off snap % went 27, 32, 25, 25, 37, 36 ,40, then 48% in the playoff game. James White was often in the 35-40% range during those 7 games, but decreased as Dion's increased, culminating in a mere 17% on Saturday.
I think these trends point to Dion being an undervalued fantasy pick next season, likely in all formats. Maybe people will look at his 7 regular season games and only see 24 targets (16g -> 55), but I'll be paying attention to these playoff games to see how that changes. During those 7 regular season games, White had 39 targets. Given the recent 7-1 split, I wouldn't count on a 55/89 target split next year between Dion/White. I think it is far more likely that Dion out targets White 2:1 than anything close to a 1:1 split. I also think it is far more likely Dion's ypc is closer to his career 4.6 ypc than his 3.15 ypc of last week.
Keep in mind Dion was on pace for over 100 rushes and 100 targets in 2015 (catch rate of 72%). And he's had double digit carries in his past 4 games. I don't expect BB to burn the candle at both ends during the regular season next year, but I do think he'll relegate James White to an afterthought role on his way to a top 20 PPR season and top 24 0PPR season (on a ppg basis if he can't stay healthy for 16 games - his main knock).
