Jose can start for the next week or so, but at the end of the day, Lowry is the better player and needs to get the lion's share of the minutes. You don't lose your starting spot because of injury. Lowry was epic before his first injury of the season, then came back too fast and wasn't the same before getting hurt again. Bring him along at a reasonable pace, but he is the starter. Jose has done a nice job of keeping the seat warm (and increasing his trade value) but at the end of the season, that is all he has done.
It is unfair to compare Jose to Bargnani, but has Jose just pulled a Bargnani 13-gamer where everyone forgets reality and starts to think he is more than what he is?
