With the performance, it seems as though quarterback Joe Flacco has found himself a great new deep threat.
Smith may be a popular fantasy option after the huge performance, but as the Ravens prepare to take on the New York Jets this weekend, fantasy owners may want to tone down the expectations for the rookie out of Maryland.
The Jets have the sixth-ranked pass defense in the NFL, led by star cornerback Darrelle Revis. That is a stark contrast from the 19th-ranked Rams pass defense.
New York's secondary is good in coverage, and the Jets also have a solid pass rush. If they can get to Joe Flacco, Baltimore's passing game would likely be neutralized.
Another thing to remember is that Smith's huge game was a stark contrast to his first two games, both of which he failed to record a single reception. It's still very possible that Smith will be nothing more than a deep threat in the mold of Devery Henderson, who has the occasional huge game but is usually never on fantasy rosters because of his inconsistency.
An alternative perspective is that Smith may have a decent chance at getting targets in this game, with top receiver Anquan Boldin drawing Revis Island. However, Smith will then draw the coverage of Antonio Cromartie, who stands 6'2" and has the speed to stick right with Smith when he's streaking down the field.
Smith could still have some great games this season, but until he performs two weeks in a row against good defenses, I'd leave him on the bench as long as I had a decent alternative.
