I don't see this possible move as one that makes sense...If we are going to pay a big salary we should have kept Jake Long, who was performing at a level comparable to Branden Albert and saved the draft pick in a deep draft.
Branden Albert was not an elite left tackle last year and was ranked #13 by PFF based on last years performance.
Jonathan Martin is a left tackle and did a fine job for Andrew Luck at Stanford...I say lets develop Martin at left tackle and draft a right tackle...which will also save some cap room versus Albert's overated salary demands (which is why KC is willing to move him).
Worst case scenario Martin doesn't pan out and we get a left tackle later, we could even double down and draft a left tackle prospect later in this draft.
This move reeks of panic to me and is a mistake.
