Isaiah Thomas Arrives in D.C. ... Limping or Swag?

Here's Boston Celtics superstar Isaiah Thomas arriving in D.C. on Wednesday for his playoff game with the Washington Wizards ... but we couldn't help noticing the way he walked off the team bus.

Some people in our office thought it looked like a limp ... like he was favoring his left leg.

Others are saying he just walks with swag -- and maybe he was just tight from the bus ride.
