While Donald Penn is the starting LT for the Tampa Bay Bucs, he has had a weight issue in the past and that issue was a problem last year and also makes the Bucs hesitant to do a long term deal with the player.
This is where the Lions jump in. Penn was tagged with a first and third round tender, essentially making it impossible for any team to sign Penn, but if he were to sign the tender, a trade is more likely to occur.
A potential deal that could happen is that Detroit parts with there fifth round selection in next year's draft and swaps second or third rounders with the Bucs, while also giving a player like Cliff Avril in the deal.
So in turn it look something like this.
Tampa sends Donald Penn, the 35th or 67th selection in the draft and Detroit Sends Cliff Avril and the 34th or 66th selection along with a conditional fifth(that could escalate to fourth) round pick, based on Penn's production on the team.
Detroit would seem willing to give Penn a extension and file away another need at little cost to the draft picks for both this and next year.
While this deal is unlikely to occur, a trade demand if not to receive an extension could push them into trading Penn, and Mayhew's smooth talking could convince the Bucs into this deal.
Also note that Penn's weight ballooned to around 370 pounds at the end of last season, but he has altered his diet and revamped his lifestyle and is has lost about 35 pounds leaving him at, 335 pounds.
Let's make the call Mayhew and smooth talk Tampa into this deal.
