Kelly continues to install spread offense

SOUTH BEND, Ind. -- Notre Dame still has a lot of work to do heading into the final five spring practices.

The Fighting Irish are still flip-flopping Trevor Robinson and Taylor Dever at offensive guard and tackle trying to determine the best combination in the spread offense, three players are competing for the backup tailback job and one of coach Brian Kelly's biggest concerns is figuring out the rotation at receiver.

"I can't tell you that's a position I'm ever going to sleep easy right now. We have a lot of work to do at that wide receiver position," Kelly said after practice on Friday.

Golden Tate, last season's leading receiver, opted to leave school a year early to enter the NFL draft. The second-leading receiver, Michael Floyd, is back. He had 44 catches for 795 yards despite missing five games with a broken left collarbone. The only other returning receiver with more than eight catches is Duval Kamara, who had 23 catches for 218 yards.

Theo Riddick, who moved from tailback, and Tai-ler Jones, an early enrollee, have been playing in the slot. Kelly said Shaquelle Evans, who played in the first five games last season then played in only one more game the rest of the season, is improving. So is Deion Walker, who had one catch for 15 yards.

"But we just need time at that position. That's one area that it's a work in progress," Kelly said.

Armando Allen, who led the Irish with 697 yards rushing last season, has separated himself from the other tailbacks, Kelly said. Jonas Gray, Cierre Wood and Robert Hughes are competing for the backup job.

Kelly believes the Irish are making progress.

"We're getting to more of a consistency to how we come to work every day. They understand what's expected more about every single day, duplicating that same intensity," Kelly said.
