4. X factors
This is a catch-all for the many things that could go wrong for the leaders. Stuff happens. Just ask Randall Tharp, the Day 1 leader who fell to second Saturday.
Tharp's lower unit went out Saturday morning, costing him precious time on the water and possibly the lead. Tharp reacted well to adversity, however, but that's not always the case. Who can forget some of Mike Iaconelli's colossal meltdowns in the face of adversity?
You can't prepare for unexpected setbacks like busted trolling motors, but you can react to them in a way that keeps your head in the right place.
There's nothing like the final day of the Classic. For the anglers in contention, it's the fourth quarter of the Super Bowl, the ninth inning in game seven of the World Series, and the final round of a prizefight all rolled into one.
All of the factors outlined here contribute to the stress. Some anglers perform well under pressure; others do not. Most of the contenders wouldn't be here if they didn't react well to this kind of pressure cooker. But the anglers who respond the best no doubt will have an edge on Sunday.
