Those concerns are unfounded - assuming your criteria is finish success rate and not style points.
McCarthy was 86% successful from 2006-2011 closing out 4th Q leads so he's improved his overall success rate 1% in the last 4 years.
He's 90% (37-4) since 2012 in 41 opportunities.
When you're talking about a pretty consistent average of 10ish chances a year, he's been 9 of 10 throughout.
