Coming off a successful 2013 season, the Detroit Lions' offensive line should be solid once again. Here are three reasons why:

1. The starters will return. The only question is at right tackle. Corey Hilliard earned the start out of training camp last year but was injured in the first game so LaAdrian Waddle took over. One of them will be the starter this year.  Both are young and only getting better.

2. Center Dominic Raiola is back and he is pumped. He was robbed of a Pro Bowl berth last year, he was that good. He seems even more motivated this season. He plays a huge role as a leader for the mostly young line.

3. Riley Reiff has a solid first season as a full-time starter. He’s only going to get better. That goes for Waddle and right guard Larry Warford too.
