One of the most frustrating things about watching the St. Louis Rams in 2010 was seeing just what they'd in the red zone and near a first down, where the offensive line seemed to spontaneously combust around Steven Jackson and the defensive backs would descend on Danny Amendola, the only guy around with decent hands. The Rams definitely attempted to address that in the 2011 NFL Draft three times, and their NFL Draft grades will mostly reflect how well that worked. TST has a great look at this, offering the logic on the picks without necessarily making a judgment.
This could mean good things for Sam Bradford's touchdown totals, if not his yards-per-attempt totals; none of these receivers are going to free themselves up downfield or outrun a cornerback into the open field, but that's not their job. (Hopefully, come training camp Donnie Avery realizes it's his job.)
The Rams come into this season with a lot of offensive uncertainty still on the books, but the same would be true if they'd gotten Julio Jones—in this case it's just been diffused into more players with a chance to impress or disappoint.
