OK, boys and girls, the 2014 fantasy football season is finally over, and the offseason changes are underway. Now it is time to move on and get to thinking about next year’s fantasy field and how you are going to dominate. And we will start this by analyzing how coaching changes will impact your IDP fantasy football season, starting this week with Jim Tomsula and Eric Mangini of the San Francisco 49ers.

This week we look at the promotion of San Francisco 49ers Jim Tomsula to head coach. Tomsula has hired a defensive coordinator. That man is Eric Mangini. And since we are concerned with how these new head coaches are going to impact our IDP fantasy teams, let’s get looking.

Mangini was once the wunderkind. Although he spent last season as the tight ends coach for the 49ers, he is of a defensive mind. From 2000-2004 he was the defensive backs coach for the New England Patriots. In 2005, he was promoted to defensive coordinator. From 2006-08, he was the head coach for the New York Jets. And from 2009-2010 hew as head coach for the Cleveland Browns.

Now he will be in charge of the San Francisco 49ers defense — a unit that finished in the top-10 in both points and yards allowed in the league in the last four seasons.

Mangini ran a 3-4 defense during his time as a head coach with the Jets and Browns. That could mean the 49ers will remain in the same defensive scheme that they have employed.

That is where the good news ends. In 2005, as defensive coordinator for the Patriots, the Patriots defense ranked 27th, according to Football Outsiders.  According to Richard Hill from Pats Pulpit, “The 2005 Patriots actually had the worst defense of the Belichick era. It was a real disappointment with a stacked-roster. That said, he does an excellent job of developing defensive backs.”

Mangini served one year as the Patriots’ NFL defense coordinator. The team finished 17th in points allowed and 26th in yards allowed. The prior year the Patriots were second in the NFL in points allowed and ninth in yards allowed. The year after Mangini’s stint as defensive coordinator,  the Patriots ranked second in points allowed and sixth in yards allowed.

In 2005, the Patriots ranked 31st in the NFL in passing yards allowed. Opposing quarterbacks posted an 87.8 passer rating against his defense.

The Mangini era as a defensive coordinator is not one to give fantasy players or 49ers fans a sense of optimism.

Consider this: Mangini has been the 49ers tight end coach for the past two years. How has that helped Vernon Davis and your fantasy team? How about 26 catches for 245 yards an two touchdowns? That was the statistics for the 49ers number one tight end for 2014. Not making me run to draft anyone under Mangini’s control.

The argument could be that Mangini has his roots in the defense. See prior stats of his time as defensive coordinator in New England.

All of that being said, the 49ers are replete with talent on the defensive side of the ball. And they will most likely employ a scheme they are familiar.

But Mangini has a way of submarining stats. So temper your expectations fantasy fans. For this particular coaching acquisition we will take a wait and see attitude.
