PIckings are looking pretty slim after 4th round

I don't suppose I know all the prospects; so, I hope to get surprised.  But, I see the Bucs are picking 28th in the fourth.  I took a look at prospects remaining, and I didn't count twenty eight! But, I find the way drafts go, prospects getting picked tends to spread out. Still, I'm thinking trade up, or forever hold your peace! There's also the issue for the Bucs that the remaining talent seems to be more Dt than anywhere else. I keep thinking we end up drafting some Qbs!
