Banister said he and Carroll discussed the need to acquire players with grit, determination and resiliency.
"That was a real good conversation for me," Banister said. "It's grit, determination and resiliency that makes an ordinary team a champion. You've got to have talent but even with talent, you have to have those qualities.
"More than anything it was a confirmation and affirmation into what I believe in as a coach. With the 21st century athlete, they want to know if you care about them and can help them get better."
Carroll has led the Seahawks to two straight Super Bowls. They won in 2014 and lost to the Patriots in the final seconds this past February. Their quarterback is Russell Wilson, who is also technically a member of the Rangers' organization as a Minor League infielder.
Wilson has never played with the Rangers but has made one-day Spring Training visits to the Rangers the past two years. Banister did not meet with Wilson on Friday.
Banister was accompanied by third base coach Tony Beasley, field coordinator Jayce Tingler, pro scouting director Josh Boyd, strength coach Jose Vazquez, video coordinator Joey Prebynski and assistant equipment manager Brandon Boyd.
