Well that is your opinion

If coming off the bench was good enough for Bobby J it is good enough for Garrett Temple.
The difference being that BJax was a classic sixth man. Energy guy who can change the complexion of a game. He was a SG in a PG's body (who rebounded much bigger) and who could get hit and spark the offense.
Temple isn't the same kind of player. Whether starting or off the bench he's more of a glue guy. Good defender, can hit from outside a bit, handles decently for a SG, makes the right pass, is usually on the right position when it comes to the team defense etc. He can be a very complimentary starter or a versatile bench player but he's not a classic sixth man.
I like him off the bench but the problem is that I really don't like McLemore or Afflalo as starters. Ben just makes too many mistakes and disappears for stretches and Arron is a bad fit, at least when Gay and Cousins are both in the lieneup and especially if Koufos is too. Just not enough spacing or ball movement. So GT is the guy I'd start just by default.
Maybe a Rudy trade and/or other deals will change the complexion of the team but for right now that's how I see things.
