They say it takes at least three years to fairly evaluate a team’s draft class, or even an individual draft pick.
So what then is the measuring stick for a blockbuster multi-player draft trade? Namely, the Rams trading the No. 2 overall pick to Washington 13 months ago in the so-called “RGIII trade.”

One year after the fact, who got the best of it?

“I think we did for sure,” Rams quarterback Sam Bradford said at the end of the 2012 season. “Just with all the picks that we have. What we’re going to be able to build. What we’ve already started to build here. I think this team is on the fast track.”

And as Rams coach Jeff Fisher sees, not all of the precincts have even reported.

“The trade is not complete yet,” Fisher said. “We still have a couple of years to take advantage of it.”

That’s because the Rams still get a first-round pick from Washington this year — No. 22 overall — as well as the Redskins’ first-round pick in the 2014 draft as part of that trade.

In March 2012, the Rams dealt their No. 2 overall pick to Washington, which used it to select dynamic Baylor quarterback Robert Griffin III.

In exchange, the Rams received Washington’s No. 6 and No. 39 overall picks last year, plus the Redskins’ first-round pick in 2013 and in 2014.

A couple of weeks after the trade, but still a month before the 2012 draft, Fisher called the deal a “perfect storm” because of the confluence of need and value. Several teams needed a quarterback entering that draft, and Griffin brought the value as an elite prospect.

One the draft began, the Rams turned the two 2012 picks acquired from Washington into four players following additional trade-downs with Dallas and Chicago: defensive tackle Michael Brockers, cornerback Janoris Jenkins, running back Isaiah Pead and offensive guard Rokevious Watkins.

The Rams’ draft haul stemming from the trade could have been even bigger. After trading down from No. 6 to No. 14 with Dallas, league sources recently told the Post-Dispatch that the Rams tried to move out of the No. 14 spot as well to pick up even more draft picks. Hey, when your franchise has lost 65 of its last 80 games, you need bodies. Lots of bodies.

Obviously, the Rams stayed at No. 14 and took Brockers. One year later, they’re not complaining.

Even with a high ankle sprain that cost him the first three games of the 2012 season and lingered for much of the year, Brockers played up to expectations and flashed Pro Bowl potential. Jenkins scored four defensive TDs and, if he avoids off-field trouble, could be a Pro Bowl-caliber player.

Pead rarely played as a rookie and Watkins was done for the year after suffering a severe ankle injury on opening day. But both players are potential starters. So for now, that makes the tally two potential Pro Bowlers, two potential starters and two more first-round draft picks for the Rams as the result of the RGIII trade.

Or six players to one.
