I get that he's been disappointing so far, but I'd still much rather have Howard than Coleman (coming from a guy who owns Coleman).
Unless Freeman gets hurt, Coleman is very clearly the 1 B (or perhaps, even the clear #2 option) in ATL. That won't change in the foreseeable future. Howard's a little dinged up -- and Cohen has been a nice surprise -- but he's still the main fiddle there. And count me among those who has at least some concern about Cohen's ability to hold up for a long period of time given his size if he keeps getting heavy usage.
So this is exactly the kind of buy low on Howard that I'd be interested in doing.
The WR swap really doesn't impact things ... in fact, for your team, I think I'd rather have Golladay too.
Your top 3 are set. Thielen is generally underrated, but it's hard to imagine a scenario where you'd bench one of your top 3 for him. Of the two choices, Golladay is the home run option (either for high upside spot starts if you think you really need a potential explosion, or more likely as trade bait that has other owners frothing at the mouth if he shows a little more like week 1 than week 2 going forward).
All of which is a long way of saying:
Give: Coleman + Thielen
Get: Howard + Golladay
I like the move.
(P.s. I'd also scour the wire this week for whatever even remotely intriguing RB might be out there to replace Lacy on the end of your bench. Assuming the obvious names are gone, one that I'd seriously consider is Alex Collins to protect yourself a little in case West misses time.)
