Job one for the Bucs this offseason: get the defense fixed. They fired Lovie Smith because he couldn't get it done, so now they'd better give defensive coordinator Mike Smith the tools to get it right -- or we'll be looking at yet another wasted season.
The Bucs fixed their offense last year almost exclusively through the draft. They got three new starters: quarterback Jameis Winston, and offensive linemen Donovan Smith and Ali Marpet. All three of them worked well, but you're not going to get three quality starters every year. You'd be lucky to get three starters in any draft, let alone three good ones.
