Tee Higgins says he's hasn't seen a change in Joe Burrow's demeanor despite the scary break-in at his place earlier this month ... telling TMZ Sports the QB "is handling it really well."
Burrow's Cincinnati pad, of course, was burglarized back on Dec. 9 -- while he was in Texas playing in a "Monday Night Football" game against the Dallas Cowboys.
The situation was disturbing -- as one of his windows was found smashed ... while one of his bedrooms was discovered ransacked.
