That's just probably your personal opinion, but statistics don't lie as Jae Crowder shoots better than Pat Connaughton.
Please refer their respective stats.

Jae is 43.6% while Pat is 33.9%, that's their last season's average, and if you look closely on the stats, Jae's percentage has improve significantly, which is opposite to what happen with Pat.
However, stats are a different side of story and It's essential for individual development of a player and that doesn't necessarily mean it could contribute to lead the team to a win.
Jae could have lesser fg attempts than Pat resulting to that figure, but as far as we are talking about PPG, Pat is a bit above than Jae, that's why I said Pat could score more than Jae.
We can't deny that Pat has been an absolutely amazing piece for the Bucks success. The very reason why he got the three-year $28.2 million dollar contract after the 2021–2022 season. So IMO, Pat has developed a good chemistry to the team already that he's confident to make his own play and create his own shot.
Nevertheless, they are both amazing player. Now, it's up to the coaching staff how they will asses their starting five.
