Point Guard market is pretty weak this summer. Lowry is at the top of the list. Toronto most likely will offer him a contract. After all they need a PG. Vasquez isn't the guy.
This ranking has Bledsoe higher.
With team playing so well as team, first choice should be signing Lowry. As I have written, if they have 25 wins at the end of the month I would be offering a 2 year deal at $9 million each year, I hope Ujiri refuses to go higher than that for any player until the Raptors are contenders to win it all.
If Lowry won't sign, I would be pretty happy to go for Stuckey with the same offer.
