Jeff Clark: The good news is there is no bad choice here. Both guys are versatile winners with the right mindset and attitude. Each has proven that they can swallow their pride and both have the ability to come in and make a difference with the second unit - in particular running the offense.
So for me it boils down to preference and fit. In an ideal world I like to have Gordon Hayward starting and Marcus Smart coming off the bench. With Horford no longer on the team, I feel like Hayward might be necessary to run some of the first unit offense.
