The Tyler Kolek's of the world are easy... Just for funsies - which point guards in the Big Ten would you trade Ty for? Straight up swap? Doesn't necessarily have to be "who's the better overall player"...simply in terms terms of overall skillset at the point guard position - Which point guards would be a better fit and be a net gain in a theoretical, nonsense fantasy-land trade?
All of the ones who average more assists per game! Just kidding.
Boo Buie and Ty Walker are both small but they are probably the 1a, 1b best overall PGs in the conference if you asked the public to vote. Hoggard is really the PG on that Michigan State team, though. Jahmir Young is a nice player, very similar player to Jayden Epps. Bruce Thornton, Dug McDaniel and Braden Smith get honorable mentions here.
That said, do I trade Ty? No way, man. But, I grow partial to players that make the choice to play for my favorite team. Don't know how I'd go trade anyone, to be honest, unless you're talking about someone who is an obvious problem or doesn't want to be here.
When I said yesterday that Ty was 2nd or 3rd best PG in the conference, I said that "statistically" he is (currently). I used player efficiency rating and turnover % because that's what I want from my PG with the roster we have. Adding another score-first guy like Ty Walker, Buie or even Young is not what this team needs imo. If someone FORCED ME WITH A GUN TO MY HEAD

to trade Ty for any of those players, I'd honestly be inclined to choose Hoggard as I think he fits what we need the most.
