Stefon Diggs set to decide on Friday

The only thing tougher than covering Stefon Diggs on the football field my be predicting his moves in recruiting.

For months, Diggs' list of potential schools has grown and shrank like an accordion, leaving fans, media and recruiters wondering.

The wonderment will reportedly cease on Friday when Diggs, No. 13 in the ESPNU 150, announces his college decision -- nine days after national signing day.

The four-star receiver from Olney (Md.) Good Counsel will provide a boost to whichever class he signs with and here are the schools hoping Diggs will give them a post-signing day surprise.

Auburn: Diggs took an official visit to Auburn on Jan. 13. The Tigers are thought to be in good position thanks in part to a close relationship the family has with ace recruiter Trooper Taylor, who would also be Diggs' position coach if he chose the school.

Florida: Some think Florida is the school to beat for Diggs, who took an official visit to Gainesville on Jan. 20. The Gators have worked hard, even overcoming a change to their offensive coaching staff when former coordinator Charlie Weis left for the head coaching position at Kansas. That caused some concerns for Diggs but it appears the Gators have alleviated them.

Maryland: There was no need to take an official visit to College Park, but Diggs did so anyway last weekend. The Washington Post reported that Diggs is expected to sign with the Terps on Friday, but it also said it wouldn't be surprising if he went with one of his other finalists. Diggs knows the nearby campus well enough so his continued interest could be telling. Diggs has been one of the main targets for Randy Edsall as he looks to shore up local recruiting heading into his second season. Still, Maryland looks like it could be the leader now.

Ohio State: Clearly, the Buckeyes got in the Diggs' race thanks to coach Urban Meyer. His impact on Ohio State recruiting can't be overstated, but Meyer and the Buckeyes will still have to overcome an incredibly short time frame. They recruited Diggs for about a month while other schools have recruited him for over a year. Diggs took an official visit there on Jan. 27.
