I'd say #89 is a lock. Someone pointed out that #5 has been getting a real look from the coaches as well. We'll keep an eye on 'em both this season. A guy can learn so much and real sense of the up and comers from watching TC.
The battle at the center position has been intriguing as well.
If I may add, #70, #46 and #1 are locks too. I think in just 6 days of TC they already have done well and prove they can play in the CFL and worthy of spots in the 44.
