The college all-star games and the NFL Scouting Combine have come and gone. The pro days, top 30 visits and private workouts are finished. After months of evaluation and hundreds of thousands of dollars spent on that evaluation, the goal line is finally here for the Rams and the rest of the league.

The NFL draft is upon us. Almost.

“A lot of hard work goes into this,” Rams general manager Les Snead said at Monday’s pre-draft news conference. “This week’s all about dotting some I’s, crossing some T’s, still talking about scenarios.”

And talking and talking, about scenario after scenario. The Rams are used to picking much higher than No. 16 overall. They usually don’t have to wait very long to make their selection, and not that much happens in front of them.

That’s not the case today. Barring the unlikely possibility of a trade up, the Rams can do nothing but sit and wait until about 9 p.m. or so while the first 15 selections are made.

“You try to anticipate what’s going to happen ahead of you,” coach Jeff Fisher said. “There’s no way that you’re going to be entirely correct. But we go through the different scenarios. That’s the process this week, is you go through and watch 15 guys come off the board and look at your options, at whoever’s left, and then you go from there.”

There are hundreds of permutations, and all it takes is one unexpected, or just different, move to trigger them. Just a few examples from a Rams perspective:

• Will zero, one or two quarterbacks go in the top 15?

• How many 3-4 defensive ends will be taken in that span?

• What about Notre Dame’s Tyler Eifert, the best tight end in the draft? Will he go in the top 15, or later?

And after the Rams make their pick at No. 16, they must turn around and select again six picks later at No. 22 overall. That’s the pick they acquired from Washington in the so-called “RGIII” trade, which led to the Redskins taking quarterback Robert Griffin III at No. 2 overall last year.

Complicating matters for the Rams —and everyone else — is the simple fact that this looks to be one of the most unpredictable drafts in memory. It’s possible there could be no skill position players taken in the top 10. It’s also possible there could be no running backs taken in the first round for the first time in nearly a half-century.

“It’s hard to predict, but we have a good feel for it and we feel like we’ve got a good board right now,” Fisher said. “We have a number of players that we think can help us there (at No. 16).”
