CHARLOTTE — Things heated up this week, in more ways than one. For starters, the team transitioned into Phase 3 of the offseason program, which means they get to wear helmets and go 11-on-11 in practice, which automatically ramps up the level these guys go at. (There's still no contact, but team drills have a different vibe.) And then Thursday, they took a field trip to Hendrick Motorsports to see the most successful team in NASCAR, which was worth it for the object lesson alone.
