In the Rams’ 19 seasons in St. Louis, few drafts have had more meaning for them than the 2014 edition. With that in mind, Rams coaches, scouts, front office executives and medical personnel have descended on Indianapolis for the NFL scouting combine, the gathering that kicks the pre-draft process into high gear. The Rams will reap the final benefits of what has become known as the “RGIII trade” in 2012. The Rams have two first-round picks — No. 2 (from Washington) and No. 13 overall — and four picks in the top 75. As NFL Network analyst Mike Mayock pointed out, there couldn’t be a better year to have extra picks. “This draft I think is the deepest in 10 years,” Mayock said Tuesday, during his annual pre-combine conference call. “That’s been reinforced by most of the general managers and scouts that I’ve talked to throughout the league. “I had one GM tell me the other day that having a top 20 pick this year is very similar to having a top 10 pick last year. So I think there’s more depth. There are certain positions that are stacked this year, and you can get a quality player through three or four rounds.” In another testament to the depth of the draft Class of ’14, one veteran scout told the Post-Dispatch at the Senior Bowl that wide receiver and return man Tavon Austin would be a second-round pick this year. The Rams traded up to No. 8 overall to land Austin in last year’s draft.
