In the world of Rams general manager Les Snead, there’s no such thing as a thin draft. And when it comes to filling out a roster, there are “wants” not “needs.” “Sometimes when you ‘need’ something, you become desperate,” Snead said. “When you’re desperate, you can make bad decisions.” Even after what looks like a good offseason a year ago in player acquisition, the Rams can’t afford bad decisions this time around. There won’t be as much roster turnover this time around. And there are fewer holes to fill. But at minimum, the Rams need another good offseason in order to become a bona fide playoff contender. In terms of the upcoming draft, the Rams reach a milepost in that pursuit with the NFL Scouting Combine, which begins Wednesday and runs through Feb. 26 in Indianapolis. For Snead and the Rams, their draft board comes into sharper focus after the drills, timing and testing, interviews, and medical exams in Indy. In some cases, they’ll get a better idea of who’s draftable — and who’s not.
