This took a while to build and figure out but I managed to build a 99 Colts TT with added players that boost others. Just posting if any other colts team players looking to build up or get the best lineup possible. Warning some cards are not cheap, mostly Kicker and Punter.
The Lineup I have built and all top row players get 99 overall plus stat boost. https://www.mut.gg/23/lineup-builder/4be554fb-2aa6-4279-b504-131431c087a1/
Cards I used to boost.
LT: AKA The Terror - Boost: +5 IBL +6 RBP +6 RBF +6 PBP Boost Both WR and TE.
C: AKA Red Tornado - Boost: +7 AGI +4 Speed +7 ACC +1 RBF Boost Both LG and RG
QB: GG Vol.2 88 Dak Prescott - Boost: +1 AWR Boost All Players
RB: GG Vol.2 Najee Harris - Boost: +1 RBK +1 RBP +1 RBF Boost All OL
CB: GG Vol.2 Isaiah Rodgers - Boost: +1 PRC +1 MVC +1 ZCV Boost All DB
P: AKA Scottish Hammer - Boost: +1 AGI +1 KPW +1 IBL +1 POW Boost All K/P, D-Line And LB's
K: AKA Legatron - Boost: +2 ACC +1 AWR +1 KPW +4 KAC Boost Both K/P and OL
Strat Items Used.
Legendary Iron Wall OL
Legendary Hybrid MLB / FS / SS
Legenday Colts Team Affinity
Now there are probably more possibilities in building a 99 overall but it's trial and error so if anyone has a better and more efficient build feel free to post it here.
Without the 88 overall Dak Prescott card in this lineup it stays at an 98 overall TT but maybe a strat card I am missing to help the +1 AWR
