With the Bills strapped for cap space (i.e. they're having a tough time signing a vet FA RT) and with only six draft picks (R1,R2,R3,R5,R5,R6) it may be wise for this new coaching staff to seriously consider placing Kouandjio at LT and Glenn at RT rather than going with the more conventional Glenn at LT and Mills at RT.
Mills was a turnstile at RT last year, arguably the worst RT in the league. That needs to be improved upon.
I know that Glenn is being paid like a LT, and therein lies the rub for the Bills' front office. But the bottom line is that the Bills should be putting the best players on the field if they hope to win more games.
Because of Kouandjio's prior knee injury, he doesn't play RT very well. However, he does seem to play LT very well.
Glenn - LT/Mills - RT
Kouandjio - LT/Glenn - RT
Glenn - LT/Ducasse - RT
Glenn - LT/Groy - RT
There are a lot of possibilities but I think that the Kouandjio - LT/Glenn - RT experiment is at least worth exploring because it may prove to be the most successful.
