The Phoenix Suns aren't going to sneak up on teams after making the biggest improvement in the NBA last season. It might not matter against the Los Angeles Lakers, who could be in even more trouble after their already short-handed roster took another hit with a devastating injury. Phoenix opens its season Wednesday night seeking its seventh straight home victory over the Lakers. The Suns won 48 games in their first year under Jeff Hornacek - a league-best 23-win improvement from 2012-13.
