I don’t think it is anything more than Gabe expanding his game in the offseason, feeling confident, and letting them fly.
I know some posters here are really against Gabe shooting so many jumpers and threes, but I think that especially with CJ out, he is having a harder time getting the ball on the block and is resorting to trying to effect the offense however he can. As you mentioned, his % isn’t awful, especially for a big guy. Who knows, maybe he gets hot in the last week and finishes the year above 40%, which in my book gives him a lot of freedom to keep shooting. Lastly, no one has made anything for Lehigh from 3 over the last week, so I don’t think it is fair to single out Gabe more than the rest of the squad.
