David Lee has been hired as Jets QB coach. League source.— Chris Mortensen (@mortreport) January 20, 2013
This is terrible news. David Lee was the QB Coach under Tony Sparano in Miami that introduced the wildcat. He's had zero success, as far as I know, developing a QB, both in Buffalo and Miami. It may not matter as much if Marty Mornhinweg is the QB guru he's supposed to be, but it's not good news. All indications were that Tim Tebow would be leaving soon, but this may, probably not, change things. We'll have more on Lee later.
