No sophomore slump yet Dan Leberfeld

Former New York Giants linebacker Antonio Pierce now works for ESPN as an NFL analyst.
On Monday’s NFL Live, he said Mark Sanchez is in “a sophomore slump.”
You can’t say that yet.
It’s just the preseason.
If he struggles once the real games start, then we can talk about “a sophomore slump.”
But until then, it’s premature to use that terminology.
