Yes. But on the right team. He could be a starter on a team with a big three where his main purpose was as a defender and all that was asked of him on offense was to spot up in the corner and cutting to the basket on double teams.
At least right now I don't see him starting on a team that needs offensive balance from all 5 positions.
Jeff Taylor can start... Hell, he started for us some last year... but we will not be a playoff team nor a very competitive lottery team if Jeff Taylor is our starting shooting guard. The stars would have to align for Jeff Taylor to be a starter on a quality team. It would have to be one of the "super teams" that finished signing big names and was looking for a cheap SG plug-in.
I assumed that by the title of the OP that the question was asking if Jeff Taylor could be an established SG in the league that would command Gerald Henderson type money in free agency. To that... my answer is no.
