Seriously, why do you say that?
First of of all, the measurements are different. While Crowder is 6'5/6'6 with a 6'9 wingspan and a 8'3 standing reach; a standing reach of a shooting guard.
Colson is 6'5/6'6 with a 7'1/7'2 wingspan and bigger standing reach(unrecorded, though he plays much bigger, so it's adequate)
The similarity starts and ends with their height and grit that the play with.
Colson is an elite high volume dominant post up player and an excellent Roll Man. He plays big and he plays inside-out or inside-in. His game revolves in the post, rolling and attacking the rim and the offensive glass. His post game consists of fade aways and jumpers mostly and some running hooks. Issue with Colson is his weak lower body imo...it doesn't enable him to get to his spots against his own matchup. It doesn't bother him in college one bit cause of his excellent effciency on his post-up fade aways. I do wonder how it's going to affect I'm in the NBA. I will add that he is absolutely unstoppable against a switch in College, so I like that.
Colson can shoot jumpers from short, mid and long rang. I wanna be careful with it, but his efficiency was really great in 20016-2017 from all 3 levels. Although in low volume and has been inconsistent from year to year. His catch and shoot when unguarded is great in College. It's tough to project how good he is going to be eventually as a shooter in the NBA. Though, you can feel optimistic because he has decent form.
Moreover, offensively he was really only looking for his own shot. He was doubled a lot in the post, but didn't show great passing out of the post or great anticipation. Also, for some reason he just doesn't screen..he only slips. So again, is that because of his skinny legs or??? I really wished he had stronger core...I think it limits his upside some what.
Not a good passer or an explosive straight line driver as well.
Colson despite his stats is not a great of a defender; Notre Dame basically hedges and followed every screen. He hedges well, but he doesn't recover very quickly. As a defender, he was mainly hedging and defending the post. Again, because of his weak lower body, he wasn't very good as a post defender...although he did show good hands in the post, hence his high stl rate.
I do think he can succeed, but he is going to need some work.
Crowder is exactly who he was in College. They play nothing a like so the comparison to me is way off.
Colson is more like a hybrid of Jarnell Stokes/Draymond Green. Like take away Green's elite passing, ball handling skills for a big, ability to run the break, passing and elite defense and replace it with a player that's longer, has an elite post up game and has an upside of being a much better all-around player in time...perhaps on both ends... just not there now. Crowder is more like Gary Clark.
