Ravens' dream first-round scenario

On our weekly Baltimore Ravens chat, I was asked to address the team's different scenarios in the first round: dream, great, good, most realistic and awful. I thought I would share my thoughts in more detail on each throughout today.

Here is the Ravens' dream scenario ... The Ravens draft Michigan offensive tackle Taylor Lewan with the No. 17 overall pick.

Let's be up front about this. The odds of this happening are 100 to 1. This is like the Cleveland Browns winning the Super Bowl. That's what makes it a "dream" scenario.

Lewan is the third-best offensive tackle in this draft behind Auburn's Greg Robinson and Texas A&M's Jake Matthews. He represents the biggest upgrade the Ravens could make at right tackle, the biggest hole on the team. Lewan also has the ability to eventually play left tackle.

So, why would the Ravens have any shot at Lewan? He is dealing with a couple off-the-field issues. His arraignment on one charge of aggravated assault and two charges of assault and battery is currently set for nine days after the draft. Lewan has also denied allegations that he intimidated a woman in 2009 who said she was sexually assaulted by one of his former teammates. These red flags could scare some teams.

Still, it's difficult to put together a mock where Lewan falls out of the first round. Mel Kiper Jr. believes there's a chance he could go as high as No. 2 to the St. Louis Rams. Even if Lewan doesn't go there, he would still need to make it past the Oakland Raiders (No. 5), Atlanta Falcons (No. 6), Buffalo Bills (No. 9), New York Giants (No. 12) and Rams again at No. 13.

The Ravens aren't banking on this happening. Assistant general manager Eric DeCosta believes the top four tackles (Robinson, Matthews, Lewan and Notre Dame's Zack Martin) will all be gone before the Ravens are on the clock. If somehow Lewan does slide, it would certainly be a dream come true for the Ravens.
