For the record, Caitlin has taken over 20 shots in a game 44 times in her career out of a little more than 100 games. Paige has attempted 20+ shots 4 times, all in her freshman campaign, with a high of 26 when she shot 15-26 against SC. In that game, SC knew Paige was going to shoot and still could not stop her. She easily could put up comparable numbers to Caitlin if she upped her attempts per game.
Herein lies the rub. It goes against Paige's nature to force her shot. I can count on one hand the number of bad or forced shots by her at UConn. Contrastingly, Caitlin forced at least 10 uncharacteristic shots, especially from the 3-pt land against K St. This is one area of difference in their games: Paige doesn't force her game to make things happen, while Caitlin wants to make things happen and sometimes forces things.
As Geno has stated previously, nobody makes Paige play at a different speed. She might not be the quickest or most athletic, but her change of direction and pace serves her well. Clark is a demon going north to south, and it's where she's most dangerous, pulling up for a long 3-pt shot or deftly assisting a teammate.
They are both generational talents. While Paige was missing last year, Caitlin picked up the mantle and brought just attention to the women's game. The reason this comparison is occurring now is because Ms Buckets is healthy and reminding everybody of her genius and prowess on the court. If Clark was wearing a UConn uniform, I would be ecstatic, but I would still rate Paige the better overall player.
Finally, Iowa's best shot at a NC was last season. There are too many talented team for Iowa to go on a similar run like last season. Also, it would be close to impossible for Clark to top last year's tourney run. If, and it is a big if, Uconn and Paige especially remain healthy, they have a more realistic shot at making the NC game than Iowa. Mostly because they have the better chess pieces.
