Q: At least Raheem Morris finally has the name of the Bucs' starting quarterback in the back of his mind.
 He wants to make sure he made the decision with his head and not just his heart.
 That's why Morris declined to name his choice between Byron Leftwich and Luke McCown on Friday until after one last consultation with his coaching staff.
 After that  Morris said  he would inform the owners  then his team before making the eagerly awaited announcement. Players were off Friday  so an announcement could come this morning.
 "We'll have a decision here in the near future " Morris said. "I think we've got to go with who we think gives us the best chance to win.
A: Raheem Morris
Rationale: Here the main entity is Raheem  Morris since the main topic of the document is about him starting as quarterback.
Q: Says he âprobablyâ has âa very good relationshipâ with  Kim 
President Donald Trump refused to say whether he has spoken directly with North Korean leader Kim Jong Un in an interview on Thursday  but said he âprobablyâ has âa very good relationshipâ with the dictator.
âI donât want to comment on it â Trump told the Wall Street Journal after he was asked directly if he had spoken with  Kim . âIâm not saying I have or havenât. I just donât want to comment.â
Direct talks between the U.S. president and  Kim  would be unprecedented. No conversation has been publicly reported between any sitting U.S. president and a North Korean leader in decades  if ever.
Trumpâs relationship with  Kim  has been primarily distinguished by escalating barbs and insults. North Koreaâs aggressive pursuit of a ballistic missile capable of hitting the U.S. with a nuclear warhead has emerged as the presidentâs most fraught foreign crisis.
Trump has mocked  Kim âs weight and called him âlittle rocket manâ in a speech to the United Nations General Assembly. He quipped on social media last week that the ânuclear buttonâ on his desk was larger than that of the North Korean leader.  Kim  has dismissed Trump as a âdotardâ and âfrightened dogâ in public statements.
White House spokespeople didnât immediately respond to questions about whether Trump and  Kim  had spoken.
Trump has said North Korea wonât be allowed to develop a nuclear missile capable of striking the U.S.  and has threatened war if economic sanctions and negotiations canât avert  Kim âs ambitions for such a weapon.
 Kim  has vowed never to give up  his  countryâs nuclear weapons  regarding them as  his  last line of defense against a U.S. invasion. Technically  South Korea and the U.S. remain at war with North Korea after the Korean War ended in 1953 with an armistice instead of a peace treaty.
A:
Kim Jong Un
