Someone mentioned they didn't think Devonte worked the middle of the field or he was shy there and that didn't seem to be what I saw in the games - dude just runs in breaker after in breaker after in breaker game in and game out which the below seems to imply:
Next Gen Stats Insight for Rams-49ers (via NFL Pro): Even leaving the game late with injury, Rams WR Davante Adams caught six of eight targets for 77 yards and a touchdown in Week 10 against the 49ers. He was productive on in-breaking routes, catching three passes on four targets for a season-high 51 receiving yards on such routes – his second game this season with at least 50 receiving yards on in-breaking routes, both coming against the 49ers (50 yards in Week 5).
He's our backside dig guy this year!
