Under coach Jeff Fisher and general manager Les Snead, the Rams have invested four picks in the wide receiver position over the 2012 and 2013 drafts — one in each of the first four rounds. And over the course of the last training camp at Rams Park, it was hard to keep your eyes off the group — spectators and media alike. • Electrifying rookie Tavon Austin, whom the Rams traded up for in the first round of the 2013 draft. • Tall, athletic Brian Quick, the first player taken in the second round of the 2012 draft. • Sure-handed Stedman Bailey, a teammate of Austin’s at West Virginia and a third-round pick last April. • Deep threat Chris Givens, a fourth-round pick in 2012 who was coming off a promising rookie year. Throw in the “graybeard” of the group, sure-handed Austin Pettis, and you had what became known as the Rams’ big five. But the Rams never turned into the wide-open, pass-happy team that was expected. Just four games into the season, the Rams scrapped a pass-first scheme that featured three-wide-receiver sets. It was replaced with a run-first offense featuring multiple tight ends. Elsewhere, players the Rams considered in those past two drafts such as Alshon Jeffery and Keenan Allen gave secondaries fits. Meanwhile, the Rams failed to have a 1,000-yard receiver for the sixth consecutive season. Who knew Isaac Bruce and Torry Holt would be so hard to replace? Even though he missed the last three games with a high ankle sprain, rookie Austin led Rams wide receivers with 40 catches. To find the last time the Rams’ leading wide receiver had fewer catches in a season, one must go all the way back to 1986. That year, Henry Ellard led the entire club with just 34 catches.
