This is the mismatch that defines Arkansas' ceiling in this tournament. They can score in transition, they can spread you out, they can attack downhill through the paint. But they can't consistently create off the dribble against elite perimeter defense, and Arizona's guards are some of the stickiest in the country.

Arizona has seen this movie before. They've played high-scoring teams, they've played teams that try to pace them up, and they've never let that change their defensive approach. Tommy Lloyd's Wildcats trust their length, trust their activity on the perimeter, and trust their ability to make every possession a grind.

Arkansas will try to run. Arizona will control the game. That's the Sweet 16.

Arkansas' strength is also their constraint. They want to play fast and create space. Arizona doesn't care about space if you're not making shots, and Arizona's perimeter length makes that difficult.

Arizona's ability to defend Arkansas' guard creation in pick-and-roll and force them into tough decisions determines early momentum. If Arizona's perimeter players can stay attached to Arkansas' backcourt without fouling, Arkansas' offense becomes one-dimensional by halftime.

Arkansas can still win if their role players catch fire, but catching fire against Arizona's length requires near-perfect shooting.

Arizona wins 68-59. Arkansas' Sweet 16 run ends because Arizona's perimeter defense and length create an environment where Arkansas' guards can't generate the free-flowing offense they need to win.
