The Gers assistant manager hailed veteran striker Kenny Miller for his consistent displays this season.
Miller has remained a vitally important player for the Scottish Championship leaders this season in the twilight of his career, scoring 16 goals in 33 appearances in all competitions.
The former Scottish international, who is in his third spell at Ibrox, has netted three times in the club's last two matches and has generally been an example of how older players should lead the way in the latter years of their career.
Weir admitted that he has been delighted with the form of Miller this season and branded him an "inspiration" to the rest of the Rangers squad.
The former centre-back told the club's website: "He has been excellent all season. His general level throughout the season though is very good, and that includes training day-in and day-out, which is obviously very important for us.
"He’s an inspiration for a lot of the guys. The younger ones see an experienced professional, and after what he has done in his career, the way he still plays and trains is a really powerful message for us. Kenny has earned a contract for next year and is looking great on the pitch just now.
"We’re really happy with him and delighted to have him here. He’s adding a great deal to the team, he’s scoring goals, creating goals and causing problems for other teams in terms of his movement as he is really difficult to pick up. That, allied to all the stuff he does off the field, means he is a massive influence for us in the whole environment we are trying to create."
Miller is enjoying a far more successful second season in his third spell at the club than he did last campaign, already nearly doubling his goal tally of eight from 2014-15.
In total, the striker, who is one of only five post-war players to play for both the Gers and their Old Firm rivals Celtic, has scored 92 goals in 220 games for the club since making his first debut 16 years ago.
His goals this season have been a key driving force for the club's promotion push, with Mark Warburton's side currently 11 points clear at the top of the Scottish Championship with a game in hand despite their defeat to second-place Falkirk on Friday night.
