Marshal Yanda?

Just thinking about potential trades coming on draft day and trying to think of possibilities that haven't been mentioned.  What about a trade for Marshal Yanda?  How about a 3rd and the Bucs throw in Doug Martin?Why it makes sense:  Yanda is in his contract year.  He was arguably the best OG in the league this past season.  He helped make Justin Forsett (previously a journeyman RB) a pro-bowler. Flacco's big money kicks in during the 2016 season, so it's unlikely the Ravens could give Yanda a big contract then. Why it doesn't make sense:  He'll soon be 31.  Do we really want another aging, retread OG?  Did Yanda just excel in Kubiak's zone blocking scheme?Thoughts?
