Tom Brady and the Tampa Bay Buccaneers have dug themselves a deep hole ahead of an important period of the season. Following their painful 7-35 loss to the San Francisco 49ers, the Bucs are 6-7 ahead of Week 15.Their struggles on the offensive end are visible to everyone and there is a growing concern about Bucs OC Byron Leftwich. Former NFL quarterback Brady Quinn has claimed that Tampa Bay were hopeful of moving on from Leftwich but failed to do so.Here's what Brady Quinn said about Byron Leftwich and the Buccaneers, as per JoeBucsFan.com:"From what I’ve heard, they were hoping maybe Byron Leftwich would get a head coaching job so Brady could have more control over things as far as playcalling goes. He hasn’t been overly impressed with that.”Quinn added:“So maybe that’s part of it; there’s some frustration there [with Leftwich playcalling].”The Tampa Bay Buccaneers have the 28th-ranked offense in the game when it comes to points scored per game. As of now, they have scored just 17.2 points per game this season. Tom Brady's numbers have also fallen off a cliff and he is quite unhappy with how things have unfolded since his return from retirement.Head coach Todd Bowles is also under a lot of pressure along with Byron Leftwich and things don't get any easier for them. They will face a stern unit in the Cincinnati Bengals in Week 15, which is going to be a tough test.CHAMPA BAY@bucsnationx21Watching this one hurts. He’s the only one motivating everyone.
