Lowry was an awesome player till he got injured. Everyone knows he's on the cusp of being an allstar and arguably a top 10 PG before injuries derailed him last year.
Like its been said before as well, Calderon is never this consistent and its a contract year and its only 5 games in which they played crummy teams as a small sample sizes. all teams go on these types of hot runs. Calderon has been with this team for this many seasons and he has had his fair share of starting gigs. There's a reason why the Raptors try to keep replacing him - he's not a long term fix.
