Seahawks defensive lineman Rasheem Green tells TMZ Sports he'd have no issues at all if his team signed Colin Kaepernick ... saying the quarterback would work well in Seattle.
"That's not really up to me," Green told us outside of JLT Performance Gym on Tuesday, "But I feel like he would be a good fit there."
Kaepernick-to-Seattle rumors have heated up this week ... after the former 49ers star threw a bunch of passes to Seahawks star receiver Tyler Lockett in a workout on Monday afternoon.
