Several factors that are currently conceivable play into this decision.
First, Jermon Bushrod is certain to command a significant salary this offseason. Most likely the figure will not be one Mickey Loomis and his staff can agree is worth the production. And Jake Long, even if he was allowed to walk by the Miami Dolphins, isn't walking through the door any cheaper.
Second, Fisher could be the second best offensive tackle in the draft, if Jake Matthews decides to stay at Texas A&M (his teammate Luke Joeckel being the first, of course). And if Matthews stays, he will almost certainly be the second lineman off the board, going in the first 10 picks.
At 15, the Saints would then be fortunate to land Fisher. The 6'7", 305 lb. senior was a dominant player in his time at Central Michigan.
He exudes unusual athleticism for his size and the position. His ability to keep his feet moving through a block in space is nearly unparalleled. Because of his remarkable skill set, he is the perfect fit for the tackle spot which is a spot the Saints love to use in space on toss sweeps and swing screens.
His overall pass-protection skills are outstanding as well. He understands angles and leverage, and uses his hands well. He also possesses long arms which help him anchor a defender.
Why Fisher Over Damontre Moore?
Based on common projections by multiple draft services, Damontre Moore and Eric Fisher were the two players available at 15 who made the most sense for the Saints.
Moore was tempting, but two factors played against him. First, though an outstanding run defender and college sack-artist, he seems to lack the elite burst that is ideal for the NFL level. He seems a better fit for a 3-4 defense which asks its ends to double as playmakers.
Second, he found himself injured in the Cotton Bowl on Friday night. Players who are injured in the college bowl season, or pre-draft process, often slip and generally do not contribute a ton in their rookie seasons.
The Saints need to find a productive starter with their first pick in the 2013 draft. And ultimately, protecting Drew Brees is the smartest pick the Saints could make in the 2013 draft.
