Not sure he's even thinking either of those thing.
Not singling you out here, as many in this topic are guilty of this, but the difference between fantasy owners vs coaching decisions seems to be that fantasy owners see players as pieces on a chess board; or maybe more accurately like player/characters in a game of Dungeons & Dragons.
It objectifies the player and dehumanizes the decision making process by breaking the players down to their most basic statistical contributions.
"Well of course Lewis will come in and take all the carries and receptions from White, making White obsolete! Lewis has a +3 Jock Strap of Anti-Itch and +4 Cleats of Juking! Plus he's got 17 DEX and 14 CON compared to White's 12 DEX and 16 CON! Sure White's constitution is worth something, but It's worth switching to Lewis for the dexterity saving throws against tackling alone! Every idiot can see that!" says the Dungeons and Drag-er, fantasy football player.
By comparison, coaches see a human being on a playing field and in practice day in & day out.
Coaches will often reward players for contributing and make returning players earn their roles or prove their ability again after a long layoff. It's not as simple as looking at a stat sheet (or character sheet) and swapping in one for the other.
IMO you're significantly short-changing White's contributions thus far in the quote above - he's clearly performed well in Lewis' absence. In my opinion, BB is highly likely to keep him involved, especially if Gronk misses time. And I'm pretty sure BB doesn't care what Lewis did last year or how many snaps he played or what his +4 Cleats of Juking do for him on paper. BB coaches human beings who have earned trust and respect through hard work.
that in part is what makes coaching decisions incredibly difficult - what seems cut and dry when looking at what Lewis did last year, while healthy, as a whole, doesn't necessarily lend insight to what BB will do with Lewis, coming back from a long layoff after a significant injury on the current Patriots roster. Even if 100% heathy, team is still relevant. Chemistry is still relevant. The Pats lost a close one against Seattle. The Seattle defense came to play and played well, especially in the final series.
Could they have used Lewis in that game? Of course they could have - he's yet another weapon. Would using Lewis have guaranteed a different outcome? Hard to say but I seriously doubt it.
Even with his +3 Jock Strap of Anti-Itch.
just making an observation about what I see as a recurring theme in fantasy sports. It's never black and white in sports. There are all kinds of gray area factors that go into coaching decisions, and they're often complicated. What seems like a no-brainer to a fantasy owner might be the most difficult decision a coach has to make all year; especially if it means demoting a hard worker who's been a solid contributor in a winning season. Some coaches won't do that.
No idea what will happen with Lewis, but some folks here are looking at this situation far too mathematically and totally losing sight of the human element IMO.
