MAL has a lot going for him apart from the shooting. We've had point guards who couldn't shoot but helped us -- KO and Taliek to name two. It's far from ideal but it can work.
I think the difference between MAL on the one hand and KO and Taliek on the other is that they were fast and MAL relies on strength, which doesn't translate as well from high school to higher levels where everyone is strong. But, MAL would be a good "big guard" to complement Akinjo and Gilbert when we need a distributor with size for defensive and end of game purposes.
Overall, if MAL would have cost us Akinjo, I'm glad we got Akinjo, but MAL is better than the likes of Anderson, and ultimately KO has to figure out how to build a complete roster. The Garrison comparison to Anderson is good, the difference is Garrison was 3rd point guard and 5th guard, Anderson was 2nd point guard and 4th guard and there was no 5th guard or 3rd point.
